I think Bradford is one of the most overrated players around. The Alex Smith analogy is a good one, only that Bradford has stronger arm. Both guys were 1st overall picks and are given the excuse of bad coaches, bad WR's, different sysems, blah blah blah.
I say if they were good QB's, they wouldn't have gone through different coaches and systems and would make their WR's look better. Peyton Manning has made guys like Austin Collie and Jacob Tamme significant. Other than a year or two of Randy Moss, what WR has Brady had? Before you say Welker, he's made Welker much more than Welker made Brady. Roethlisberger's best WR's, Buress and Holmes, have been allowed to walk and he just moves on to the next guy.
Factor in that Bradford has had the threat of a running game with Steven Jackson, his development should have been accelerated bceause teams are focussed on stopping him. If Bradford doesn't turn it on the 2nd half of this year, I wouldn't be surprised to see Fisher move on and use one their multiple 1st round picks on a QB.
