I think it will be a interesting game.
As a huge Chiefs fan this is how I think it will break down ( no one really knows but my thoughts..)
Bills are a momentum team, not every game but the majority of your games when you smell blood your team just stomps on the team and put them out of their misery. Allen seems to play really well when he is up or not feeling much pressure in a game. When he sees the defense is on (which is usually is) then he plays great. Seems like when he gets nervous he starts to press, when he presses he does not play well. Your ups and downs are much more dramatic, doing what you did to the Pats last week, absolutely amazing, then losing early in the year to the Jags, not so good.
The Chiefs have not lost to any bad teams, especially when you talk about when we played them, obviously the Bills, but playing the Ravens with most of their good players including Lamar, Cinci, titans, and the Chargers, all of these teams are Playoff teams ( except the chargers but should of been easily if it wasn't for their coach ) so we haven't have any bad loses to bad teams. Meaning the Chiefs haven't lost to bad teams this year.
Seems like its really going to come down to momentum. If the Bills get it early and say you get up by 10 or more in the first half, the game will probably be over. I think who gets up early and gets momentum wins. I'm hoping for a Chiefs win but have a very bad feeling about it, I put $100 on the Bills to win straight up to hedge my feelings/money... LOL Good luck boys!
