At this point I'd be disappointed if they didn't win at Miami.
Having lived on the West Coast for over 30 years and having attended many Bills' games out here, I say the San Diego game is the least likely to win. They rarely win out here.
I have attended games in SF, SD, LA, Oakland & Seattle and they've lost every game. (I did not attend the Kelly/Steve Young offensive explosion in SF and they won)
I am not going to SD for that game so they have a shot.
