And some people here say the Bills are overlooked.
The early indications are that Mahomes is on the right track to suiting up for the Chiefs in a bid for his second Super Bowl appearance in as many seasons. And make no mistake: Kansas City will not bow out easily if No. 15 is under center, even at less than full speed. The thing is, Mahomes himself is no guarantee of a return trip to Super Bowl Sunday. The superstar quarterback has been just a touch looser with the football since mid-December (three fumbles, four interceptions), and Buffalo's defense is coming off an inspired rout of the Ravens. Even more threatening is the Bills' offense, which has rivaled the Chiefs at times in terms of sheer explosiveness. Andy Reid's squad is superior on paper, but this feels like the season where Sean McDermott finally and fully rises to the occasion.

Anyway, I've gone 16-1 picking Chiefs games this year, so I think that's good news for Bills fans that I'm picking Buffalo but who can be sure? The last time the Bills made it to the Super Bowl, they did it by beating the Chiefs in the AFC title game, so I'm riding with history here.
The pick: Bills 27-24 over Chiefs
