Chiefs have a crowd and a big one at that. They have been the only nfl team to have a homefield crowd all season.
I did just read this on the BIlls defense
The Buffalo defense has improved as the season has gone on and ranks 12th in the NFL in DVOA against the pass. Still, I can't help but notice that Buffalo's improvement on defense has coincided with a run of games against San Francisco, Pittsburgh, Denver, New England, Miami, Indianapolis and Baltimore. Of those seven opponents, none rank in the top half of the NFL in passing DVOA on offense. Indianapolis, at 16th, is the highest-ranked passing offense of the seven. Kansas City ranks second, behind Green Bay.
I read there might be a lot of Bills fans at the game
