I guess the window was still open after all. Probably wide open in fact. Remember all that preseason talk of how the Buffalo Bills' window for winning had closed, how it was over for them, how the roster turnover would change the team's fortunes and that they couldn't get past those losses on the field in the playoffs and on the roster?

Bills: Yes, the Bills are 9-2 and the Chiefs are 9-1, but head-to-head wins have to count for something, and Buffalo has won six straight games after beating Kansas City at Highmark Stadium, where the Bills are 5-0 this season.

Should Kansas City Chiefs, Buffalo Bills or Detroit Lions be ranked No. 1 now? For first time this season, there's debate.
