The one criticism I now have of Cassel is that he and Moss don't seem to have the rapport of Moss and Brady. You'd always see those two together on the bench, whereas now Moss is over talking to someone else.
That said, I was highly critical of Cassel after the Dolphins game and I still believe that he was a significant contribution to that loss - the Dolphins never would have run that option crap if Brady had been behind center because they knew it would have been a major risk they couldn't take, whereas Cassel couldn't move the ball as well as Brady.
Which leads me to my next point, which I'm as guilty of as anyone. We/I have been comparing Cassel to Brady, who is probably the greatest quarterback who has ever played the game. What we/I need to do is compare him to an average NFL quarterback, and compared to them he floats around the median, which isn't bad but isn't great - but there aren't many good QBs in the league anymore anyways. Cassel gives the team a chance to win. Against anyone the Patriots play. He isn't going to pull wins out of his ass like Brady does, but he isn't so bad that he's going to hand games to the opposition, either.
