Looking back, losing to the Chiefs game 6 may work to the Bills advantage now. Winning then may have kept us alive for the #1 seed but we ended up #2.
You wonder if the Bills have an edge mentally with revenge on their minds and the underdog role. KC is confident, maybe too much so (a' la Hill's comments about the super bowl) and thinking they beat us once, Bills can't stop the run, Josh is not that good etc.
To me the Bills team now is so much better than the game 6 team with key players back, offense and defense paying better and more confident. Our coaches learned from that game too and think are game plan will be much better.
I actually feel really good about the Bills chances this week.
Go Bills.
