Patriots, yes. The Bills though? Even at their best, they were bridesmaids. The 0-4 Superbowl run is all they've got. I've always remembered them as being cursed, and never being able to reach greatness. They're like the Toronto Maple Leafs of football, with their fans going "Remember all those times we almost won?", with the difference being that the Bills actually have made the Championship finals in modern times, and the Leafs actually have Championship banners from a 1000 years ago. Both franchises are pretty big losers though.
The only comfort they have is knowing that at least they're not the Clippers.
