The NFL will announce its MVP in a couple of weeks, three days shy of Super Bowl LIX, and it’s virtually guaranteed to be someone who won’t be playing a competitive football game for the next eight months.Bills quarterback Josh Allen is the odds-on favorite, of which he’s certainly deserving — you know, since it’s a regular-season honor and all. His exit from the playoffs doesn’t subtract from that, and, besides, the Bills-Chiefs AFC Championship Game was entertaining as heck.But can we also acknowledge something else?Only one quarterback played at his best Sunday, and it’s the guy who tends to play at his best this time of year.The response to a thrilling AFC Championship Game, which the Chiefs won 32-29, is that we witnessed some sort of knock-down, drag-out battle between two quarterbacks who always embrace and provide drama when they meet. But really? In a proposed matchup of quarterback heavyweights, Allen didn’t hold up his end of the bargain this time.Patrick Mahomes did. His season marches on.

But Sunday’s conference title game is the one that got away from him — even more than the 13-second miracle. In that Divisional Round classic three years ago, the best football game I’ve ever witnessed in person, Allen did everything he could to win.He left some meat on the bone Sunday.For starters, the outcome rested in his hands with threeplus minutes to play, and he couldn’t even advance the Bills to midfield.But Buffalo was fortunate just to have a chance.The first two passes Allen threw should’ve been intercepted. It’s remarkable the second wasn’t picked — he couldn’t have hit Chiefs cornerback Nazeeh Johnson in a better spot. Allen had a seasonhigh three turnover-worthy passes in the game, per PFF, which also graded it as his worst game of the season. How about that?There were five fumbles Sunday, and the Bills, in a minor miracle, recovered all five. And they still lost. Allen was responsible for three of those gaffes, by the way, including a snap he just plain dropped.Allen graded out as the second most effective runner in the NFL this year in terms of expected points added (EPA). He totaled 59.3.But his total on Sunday: -2.3, his worst mark of the year.For all of the subplots in ...
