DENVER – Donning gray caps that declared them AFC East champions for the first time since 1995, the Buffalo Bills acted like this was old hat. “To be the team and to be the quarterback on the team that does it, obviously feels really good. “But there’s still a lot on the table.”Buffalo coach Sean McDermott said he received a congratulatory email from Marv Levy, the last Bills coach to win the AFC East. He also missed the 51-yard field goal attempt way to the right on Denver’s opening drive. Broncos: visit the Los Angeles Chargers, who they rallied from a 21-point deficit to beat on Nov. 1 with a touchdown as time ran out.
