For all of you J.P. Losman haters out there you are going to wish he stayed in town if something happens to Trent Edwards now.  The Bills have signed 26-year old Ryan Fitzgerald to back up Edwards in 2009.  He played in 13 games (12 starts) with the Bengals last season and he completed 221 of 372 passes (59.4%) for 1,905 yards with 8 TD passes and 9 interceptions (70.0 QB Rating).  He also carried the football 60 times for 304 yards (5.1 ypc) with 2 TD runs last season.  Fitzgerald has now played in 19 games (15 starts) in his NFL career and he has completed 297 of 507 passes (58.6%) for 2,682 yards with 12 TD passes and 17 interceptions (66.9 QB Rating).  He has also carried the football 77 times for 368 yards (4.8 ypc) with 4 TD runs.  The Bills should have signed someone better than Fitzpatrick.
