I like to distinguish between things that are predictive and things that are descriptive. Honestly, I don't think there's anything magical about the playoffs that makes people perform worse. From a predictive standpoint, I think we'll have a better idea of how a guy will perform in any given week by using a large sample size that includes the regular season than by using a small sample size that limits itself to the postseason. I think any definition of "clutch" or "choker" is bound to be a curious one, because it's going to tell us Manning is a choker for wetting the bed today against Seattle while completely ignoring the fact that two weeks ago he put up a better performance against New England than any team has ever managed against a Bill Belichick-coached Patriots squad. I think it's a curious thing when one bad performance means you're a choker, one good and one bad performance means you're a choker, and two good and one bad performance also means you're a choker. I think the goalposts, the definition of what qualifies as success or failure, keep getting shifted for Peyton- Peyton sucks in big games, with "big games" getting defined as games where Peyton sucks. Peyton rules against the Pats in the AFCCG? Must not have been a big game. Peyton wets the bed in the Superbowl? Can't handle the pressure!Manning played terrible. Again. In the playoffs.When "choke" and "collapse" are defined as not winning the Super Bowl on a team that would probably be about 15th best in the NFL with an average QB it's pretty easy for anyone to fall into that category.
Congratulations on betting the field and being right, as if that's some kind of accomplishment.
Realistically, the choke thing is just a little jab at players we don't like that much. It's not necessarily a word that describes all his performances.
But the bottom line is that Peyton has had a very, very disappointing postseason career, and it tarnishes his legacy. The degree to which it tarnishes his legacy will be debated for the next 50 years. But I thjnk everyone can now agree that overall, he's been a disappointing post season player.
With that said, the NFL isn't all about predictive statistics. It's not all about saying what will happen tomorrow. In many ways, the NFL is the league that John Facenda built. In many ways, the NFL is about mythology and hagiography and narratives and larger-than-life events and fuzzily-remembered histories. And from a "descriptive statistics" standpoint, there's no arguing that Peyton Manning's postseason career has been a massive disappointment. It doesn't mean I don't think that he's the greatest ever (again, from a "predictive statistics" standpoint, I'd gladly take Peyton to quarterback my team in any game and let the rest of the league have whoever else they wanted), but it does mean that Peyton Manning has underachieved, and that given how good he is and how many chances he's had, we would have expected better results. In large part, random is random, and we're going to see career outliers crop up like Peyton's postseason winning percentage (or Schottenheimer's, for that matter). But while I can easily sit here and say that stuff happens and it's not necessarily a reflection of the people involved, I also bet you that Peyton would gladly trade a couple of his MVP trophies for one of Eli's SB rings.
