Since we are a mere 24 hours away from the start of the NFL Divisional Round playoffs, I will dispense with any long-winded explanation of how my data loving robot (Beadle) came up with her predictions for those games.
Suffice it to say, despite her Bayesian roots, Beadle is rather lazy statistician who typically eschews the rigors and challenges associated with building statistical models from scratch for the convenience of cribbing off the work of others.
Why do all that work when you can have others do it for you?
There is no better arena to award Beadle’s sluggardness than predicting NFL football games, as there are literally hundreds of statisticians, data modelers and highly-motivated gamblers who publicly share their methodologies and resultant game predictions for all to see.
Why reinvent the wheel?
With this frame-of-mind, Beadle has all season long been scanning the Web for these game predictions and quietly noting those data analysts with the best prediction track records. Oh, heck, who am I kidding? Beadle stopped doing that about four weeks into the season.
What was the point? It was obvious from the beginning that all, not most, but ALL of these prediction models use mostly the same variables and statistical modeling techniques and, voilà, come up with mostly the same predictions.
FiveThirtyEight’s prediction model predicted back in September that the Kansas City Chiefs would win this year’s Super Bowl over the New Orleans Saints. And so did about 538 other prediction models.
Why? Because they are all using the same data inputs and whatever variation in methods they employ to crunch that data (e.g., Bayesians versus Frequentists) is not different enough to substantively change model predictions.
But what if the Chiefs are that good? Shouldn’t the models reflect that reality?
And it can never be forgotten that these NFL prediction models face a highly dynamic environment where quarterbacks and other key players can get injured over the course of a season, fundamentally changing a team prospects — a fact FiveThirtyEight’s model accounts for with respect to QBs — and the reason for which preseason model predictions (and Vegas betting lines) need to be updated from week-to-week.
Beadle and I are not negative towards statistical prediction models. To the contrary, given the infinitely complex contexts in which they are asked to make judgments, we couldn’t be more in awe of the fact that many of them are very predictive.
It is from these prediction models that Beadle aggregated their NFL team scores to generate her own game predictions.
Beadle’s Predictions for the NFL Divisional Playoffs
Without any further adieu, here is how Beadle ranks the remaining NFL playoff teams on her Average Power Index (API), which is merely each team’s standardized (z-score) after averaging the index scores for the eight prediction models:
And from those API values, Beadle makes the following game predictions (including point spreads and scores) through the Super Bowl:
No surprise: Beadle predicts the Kansas City Chiefs will win the Super Bowl in a close game with the New Orleans Saints.
First, an apology to my wife. The above photo was the one of the few Miami Dolphin-related public copyright photos I could find on short notice. It should not be regarded, however, as an endorsement of fake smiles.
Now, to the issue at hand…
Alabama’s Tua Tagovailoa was the fifth overall pick and second quarterback taken in the 2020 National Football League (NFL) draft.
Drafted by the Miami Dolphins, Tagovailoa was drafted behind Heisman winner Joe Burrow (QB — Cincinnati Bengals) and Ohio State’s Chase Young (DE — Washington Sea Dogs) and was one of four quarterbacks selected in the first round. San Diego took the third quarterback, Oregon’s Justin Herbert, as the sixth overall pick and Green Bay— mysteriously — thought Utah State’s Jordan Love, the 26th overall pick and fourth quarterback taken, was that final piece needed for the Aaron Rodgers-led Packers to win another Super Bowl (…and, even more mysteriously, Love’s clipboard-holding skills seem to be what the Cheeseheads needed this season).
Normally when an NFL team drafts a quarterback as high as fifth, they give him at least a few years to earn his first round contract. The Tampa Bay Buccaneers gave first overall pick Jameis Winston five years, as did the Tennessee Titans with second overall pick Marcus Mariota. Sam Bradford and Mark Sanchez were offered four years to prove their value to their respective teams, the St. Louis Rams and New York Jets. The oft-injured Robert Griffin III — the Washington Federals’ second pick in the 2012 draft —had three years. Even purple drank jugging rumors didn’t stop JaMarcus Russell from getting two solid years of opportunity from the Oakland Raiders.
And, keep in mind, the Dolphins’ 2012 first round pick — and current Titans quarterback — Ryan Tannehill gave the team six mediocre seasons before they jettisoned him in 2019. The Dolphins were patient with Tannehill — who has turned into a high-quality quarterback — so why not with Tagovailoa?
Yet, if he allows his football team’s brain trust to draft another quarterback in the first round, he will get more than drama, he will completely undercut the already fragile confidence of his current starter in Tagovailoa.
So why are a significant number of NFL draft experts seriously recommending the Dolphins use their third pick in the 2021 draft on another quarterback? Writing for ESPN, three out of seven experts said the Dolphins should use their pick on another quarterback:
Jeremy Fowler, national NFL writer: Quarterback. Key word is “address.” Miami needs to thoroughly evaluate the top quarterbacks in the draft, then weigh the pros and cons of not taking one and sticking with Tagovailoa as the unquestioned starter. Miami owes it to its fans and organization to at least do that. This is the one position where a surplus isn’t a bad thing. Keep drafting passers high if necessary. Tua might be the guy regardless. And if the Dolphins decide he’s better than Zach Wilson or Justin Fields or Trey Lance, then grab the offensive tackle or playmaking receiver Miami needs around him.
Mike Clay, fantasy football writer:: Quarterback. You don’t have to agree with me on this, but I’ve always been in the camp of “If you’re not sure you have a franchise quarterback, you don’t have a franchise quarterback.” From my perspective, we don’t know whether Tua Tagovailoa is the answer, as he didn’t look the part and was benched multiple times as a rookie. Miami’s future looks bright after a 10-win season in Brian Flores’ second campaign, so it’s unlikely this franchise will be picking in the top five again anytime soon. If they aren’t convinced Tua is the franchise quarterback, they need to avoid sunk-cost fallacy and a trip to long-term quarterback purgatory.
Seth Walder: Quarterback. Tagovailoa still might pan out, but quarterback is too important for Miami to put all of its eggs in that basket, especially after he finished 26th in QBR and clearly did not earn complete trust from the coaching staff. Take a shot at whichever of the top three quarterbacks is left on the board while keeping Tagovailoa, at least for now. That way, Miami can maximize its chances of finding its franchise QB.
And the question must be asked, why? Has Tagovailoa grossly under-performed? If Miami drafts another quarterback just a year after getting Tagovailoa, the only conclusion one can make is that the Dolphins consider him a bust, but with only a year under his belt is that even possible to know?
Tagovailoa’s First Year is Average by Recent Franchise QB Standards
Before assessing Tagovailoa’s performance in his rookie season, we should consider the possible comparisons. The first comparison is the most obvious: compare Tagovailoa to other quarterback’s first significant playing year (which I define as a quarterback’s first year with at least three starts and 50 or more pass attempts — admittedly, this is a low threshold).
Also, for comparability sake, I’ve decided here to only compare quarterbacks drafted in the first round since 2005, the year in which www.pro-football-reference.com starts computingESPN’s Total QBR Index (QBR) for quarterbacks. While other quarterback metrics have been posited as better measures of quarterback quality — passer rating, adjusted net yards per pass attempt — none are perfect as they don’t directly account for the style of a team’s offense, the quality of a team’s personnel, and the quality of the defense, all of which play a significant role in how a quarterback plays. In the end, I went with the statistic that best predicts wins: ESPN’S QBR.
[I should add that while the QBR does not consider the strength-of-schedule (SoS) faced by a quarterback, it is easily computed and nicely demonstrated in a past analysis by Chase Stuart on footballperspective.com. In a follow-up to this essay, I will incorporate SoS information into player performance metrics for the 2020 season.]
The second comparison is Tagovailoa’s from game-to-game. Did he improve? And the final comparison is the value of the QBR itself. By design, ESPN’s QBR is an approximate objective standard by which to judge quarterbacks: QBR’s exceeding 50 represent above-average quarterbacks when compared to all quarterbacks since 2006.
I will dispense with the last comparison first: Tagovailoa’s rookie year QBR, based on nine starts, 290 pass attempts, a 64.1 percent completion rate and 11 touchdown passes against five interceptions is an above-average 52.9 (which puts him at 26th out of 35 quarterbacks for whom the QBR was computed).
Well, on this comparison at least, Tagovailoa does not stand out in a positive way. But perhaps his performance improved over the season? Hard to say. His first start in Week 8 against the Los Angeles Rams — the NFL’s best passing defense — led to a 29.3 QBR, and over his next eight starts he achieved QBRs over 60 against the Arizona Cardinals (Week 9, QBR 87.3), the Los Angeles Chargers (Week 10, QBR 66.5), the Cincinnati Bengals (Week 13, QBR 74.5) and the Las Vegas Raiders (Week 16, QBR 64.4). Conversely, he struggled against the Denver Broncos (Week 11, QBR 22.9), the Kansas City Chiefs (Week 14, QBR 30.2). and the Buffalo Bills (Week 17, QBR 23.3) — all good passing defenses.
After these first two comparisons, it is hard to decide if Tagovailoa is going to be Miami’s franchise quarterback for the future. As with almost any rookie quarterback, there are positives and negatives, and neither overwhelms the other in Tagovailoa’s case.
However, in our final comparison, I believe Tagovailoa has more than proven it is far too soon for the Dolphins to spend a Top 3 draft choice on another quarterback.
First, we should look at the season-to-season QBRs of quarterbacks who are arguably “franchise” quarterbacks and who were picked in the first round (see Figure 1 below). And if you don’t consider Kyler Murray, Ryan Tannehill, Baker Mayfield or Jared Goff franchise quarterbacks, check in with me in a couple of years. All four are currently in a good, mid-career trajectory by historical standards.
Figure 1: Season-to-SeasonQBRs for NFL “franchise” Quarterbacks Selected in the 1st Round since 2005
Three things jump out to me from Figure 1: (1) Franchise quarterbacks rarely have seasons with dismal overall QBRs (<40), (2) Aaron Rodgers really is that great, and (3) Patrick Mahomes, still early in his career, is already in the QBR stratosphere (…and he almost has nowhere to go but down).
How does Tagovailoa compare to my selection of franchise quarterbacks and non-franchise quarterbacks, as well as the other quarterbacks in the 2020 first round draft class (Joe Burrow and Justin Herbert)? As it turns out, pretty good (see Figure 2).
As for the non-franchise quarterbacks, my most controversial assignments are Cam Newton and Joe Flacco. I’m welcome to counter-arguments, but their inclusion in either group does not change the basic conclusion from Figure 2 with respect to Tagovailoa.
Figure 2: Season-to-SeasonQBRs for NFL “franchise” & “non-franchise” Quarterbacks Selected in the 1st Round since 2005
In comparison to the other quarterbacks and their first substantive year in the NFL, Tagovailoa’s 2020 QBR is slightly below the average for franchise quarterbacks (52.9 versus 54.6, respectively), and is significantly higher than for non-franchise quarterbacks (52.9 versus 46.1, respectively).
Among his 2020 draft peers, Tagovailoa’s QBR is comparable to Burrow’s (who missed six games due to a season-ending injury), but a far cry from Herbert’s (QBR = 69.7), who is already showing clear signs of super stardom ahead.
Experts are happy to debate whether Tagovailoa has the ability to “throw guys open,” or whether the level of receiver talent he had at Alabama masked his deficiencies. He may well never be a franchise quarterback by any common understanding of the category.
But given his performance in his rookie campaign and how it compares to other quarterbacks, it is unfathomable to me that the Dolphins could entertain even the slightest thought of drafting a quarterback in the 2021 draft. I hope they are not and it is merely some ESPN talking heads with that wild hair up their asses.

Opinion journalists, such as movie critics, bring biases to every opinion they hold and complete objectivity is an ideal few, if any, attain.
The scientific literature on this trait common to all humans, not just opinion journalists, is vast and well-established. The lenses through which we interact with the world are multilayered and varied, each of us with our own unique configuration.
The science tells us we tend to overestimate our own knowledge while underestimating the knowledge of others (“Lake Wobegon effect“); we tend to believe an idea that has been repeated to us multiple times or is easy to understand, regardless of its actual veracity (“illusory truth effect“); we overestimate the importance recent information over historic information (“recency effect“); we offer our opinions to others that will be viewed more favorably by them and often suppress our unpopular opinions (“social desirability bias“); and perhaps the most dangerous bias of all: confirmation bias — our inclination to search for, process and remember information that confirms our preconceptions to the exclusion of information that might challenge them.
But nowhere are human biases more socially destructive than when opinion journalists project onto others the motivations for their personal opinions and actions. It is often called the illusion of transparency and it occurs when we overestimate our own ability to understand what drives someone else’s opinions and behaviors. [The other side of that same bias occurs when we overestimate the ability of others to know our own motivations.]
The illusion of transparency often leads to fundamental attribution errors in which the explanations for the opinions and behaviors of others is falsely reduced to psychological and personality-based factors (“racist,” “sexist,” “lazy,” “stupid,” etc.).
In combination with intergroup bias — which takes the illusion of transparency to the group level and causes members of a group to give preferential treatment to their own group, often leading to a group’s intellectual atrophy as they make it difficult for new ideas to be introduced into the group — this tendency to falsely infer the motives of others can create systematic, group-level misunderstandings, leading potentially to violent social conflicts.
Judge not, that ye be not judged (Matthew 7:1-3 KJV)
I know something of these biases as I engage in when I write, including in my last opinion essay about the unusual proportion of male movie critics that gave Wonder Woman 1984 (WW84) a positive review (“Are movie critics journalists?“). Though having never met one of these male movie critics, I still felt comfortable attributing their positive reviews to WW84 as a product of being handpicked by WW84’s movie studio (Warner Bros.) for early access to the movie, along with their desire to “please their editors and audience” (a presumed manifestation of the social desirability bias) and other career motives.
Was I right? I offered little evidence beyond mere conjecture as to why the few early negative reviews for WW84 came almost entirely from female movie critics (I basically said liberal men are “useless cowards“). For that I am regretful. I can do better.
Yet, I still believe there was a clear bias among some movie critics in favor of WW84 for reasons unrelated to the actual quality of the movie. How is it possible that, out of the 19 male movie critics in Rotten Tomatoes’ “Top Critics” list who reviewed WW84 in the first two days of its Dec. 15th pre-release, not one gave WW84 a bad review. Not one.
If we assume the reviews were independent of one another and that the actual quality of WW84 warranted 80 percent positive reviews (an assumption purely for argument’s sake), then the probability that we’d get 19 consecutive positive reviews from the top male movie critics is a mere 1.4 percent ( = 0.8^19). If we use WW84’s current Rotten Tomatoes score among all critics of 60 percent as our assumption, that probability goes to near zero.
I can only draw one conclusion: Early reviews by the top male critics were excessively positive for WW84.
Do I think editors, peer pressure, and even the general public mood weigh heavily on movie critic reviews? Absolutely, yes, and scientific evidence in other social contexts suggest this is likely the case.
Which is why when I read other journalists and movie critics suggest that negative WW84 reviews are motivated by deep-rooted sexism, I cry, “Foul!”
No, critics of “Wonder Woman 1984” are not sexist
In a recent article for Forbes, movie critics and screenwriter Mark Hughes concludes that much of the criticism of WW84, especially from male critics, is motivated by nothing less than sexism. He writes:
“Questions of the film’s tone and action sequences are frankly of little interest to me, since most of the same folks offering up those complaints were eager to praise the silliness of many other superhero films. One day it’s “these films take themselves too seriously,” and the next it’s “this film is silly and should take itself more seriously.” Wash, rinse, repeat as necessary (or as clicks and payday necessitate).
Likewise, when men helm films we see far more willingness to weigh “that which works” as more important than “that which doesn’t work,” and allow them room to come back later and impress us. A woman, though? Not so much, as Patty Jenkins has been personally insulted and condemned by voices declaring Wonder Woman 1984 an inexcusable offense to humanity. If you think I’m being hyperbolic about the accusations hurled against the film and its defenders, go look around social media and press coverage for 30 seconds, and then come back to finish this article…”
In other words, according to Hughes, we don’t have to be conscious of our deeply ingrained, latent sexism to be subject to its power. Merely disliking a movie directed by a woman proves its existence.
Let me start by noting that many of the male (and female) movie critics that did not like WW84, gave glowing reviews for director Patty Jenkins’ first Wonder Woman movie in 2017. Chris Stuckmann is as good an example as any in the flaw of Hughes’ sexism charge: Stuckmann’s 2017 Wonder Woman review. His WW84 review.
Did Stuckmann’s latent sexism only kick-in after 2017? Of course not. The more likely explanation is that Stuckmann realizes Wonder Woman (2017) is a very good movie and WW84 is not.
But since Hughes is carelessly willing to suggest critics like Stuckmann are driven by subconscious sexist tendencies when they review movies by female directors, let me conjecture that Hughes had a much more powerful motivation for giving WW84 a good review.
Hughes is a screenwriter (as well as being a movie critic) and one of the well-known attributes of Hollywood culture is that directors, writers, and actors do not publicly like to piss on someone else’s work. It can be career suicide, particularly when that person directed one of the best movies of 2017 (Wonder Woman) and is widely admired within the industry. Even if sexism is alive and well in Hollywood (and I have no doubt that it is), by virtue alone of having helmed two great movies in her young career — Monster (2003) and Wonder Woman (2017) — Jenkins possesses real power by any Hollywood standard.
That Hughes liked WW84 is not surprising. I would have been stunned if Hughes hadn’t.
My complaint about Hughes’ recent Forbes article chastising the “harsher” critics of WW84 is not that Hughes thought WW84 was a good film. That Hughes appreciated the positive themes in WW84 enough to overlook the movie’s obvious flaws is truly OK. [My family, myself notwithstanding, loved the movie.] I’ve loved many movies that, objectively, were rather bad (Nicolas Cage in The Wicker Man comes to mind).
My problem with Hughes (and, unfortunately, far too many writers and journalists at present) is that he throws around psychological theories and personal accusations without a shred of empirical evidence.
Hughes doesn’t know the motivations for why someone writes a critical review any more than I do.
But Hughes takes it one step farther. He implies there’s a dark, antisocial aspect to someone who doesn’t like WW84. He asks: “Do you look at the world around you and decide we need LESS storytelling that appeals to our idealism and posits a world in which grace and mercy are transformative, in which people can look at the truth and make a choice in that moment to try to be better?”
No, Mr. Hughes, I do not think we need LESS storytelling that appeals to our idealism and better angels. But I believe we need MORE GOOD storytelling that does that. Unfortunately, in my opinion, WW84 does not meet that standard. Furthermore, when Hollywood and our entertainment industry does it poorly, I fear it risks generating higher levels of cynicism towards the very ideals you (and I) endorse.
As one of my government bosses once said as he scolded me, “Kent, good intentions don’t matter. I want results.”
I think that dictum applies to Hollywood movies too.
