I think we need to give Edwards one more year. He was progressing fine last year before the Cardinals game when he got his head bashed in.
There are only a few GREAT qbs in the league. I count 2 future HOF QB's, Brady and Manning. (Excluding Farve) I think many of the young QB's are just coached and developed better. Perhaps Losman might have been successful if he were handing the ball of to the BUS (like Big Ben) in his rookie season under the leadership of Cohwer. He built confidence and blossomed into a real NFL player.
Are you telling me that Matt Cassell is naturally just better than Edwards?? I think not. I bet Losman OR Edwards could have thrived in the Pats system. Good coaches, good teammates, good front office, and a good owner.
I believe Edwards has good teammates. Too bad he lacks the rest. Fate of being a Bill could have ruined Losman's and Edwards career.
