I think the problem lies in when people take the anger to the extreme and it effects other parts of their lives. I'm pissed whenever the Bills lose, but I'm not going rant and rave and B word about it to my friends and family constantly. I'll be pissed for an hour or so after the game, then just say "maybe next week", of course I've been saying that all too often lately.
As far as things that happen during the week with the Bills, there's nothing I can do about it. I'm not mad Trent is gone, I'm actually happy. I question the Kelsay signing, but I don't swear up and down and give up on the Bills. You have to realize, they aren't going anywhere this year, its a complete rebuilding year. You take that into perspective and you know they are going to lose a hell of a lot more than win this season.
Nix and Gailey seem to be taking the approach that they are seeing who is and isn't worth keeping around for future years. This is a rebuilding process that will take a few years to complete.
