The Bills have signed quarterback Ryan Fitzpatrick to be the backup to Trent Edwards. "I think it's helped me a lot in my career to play behind Marc Bulger (in St. Louis) and Carson Palmer," Fitzpatrick told the Bills' official team Web site. "I've been able to see how they approach the game, and in doing that I've been able to help them out. I think that's what I'm going to bring here. "Trent is still a young guy and I'm going to help him out with his preparation. I'm going to be his eyes when he's on the field and I'm looking forward to that relationship."
