Out of curiosity, I jumped on a Cardinals forum to see what they thought about Dobbs. Basically, they don't like it but, that seems to be based on the general gist that they don't know anything about him except that he's been a 2nd-3rd string QB on 5 different teams.
The more interesting find was that several people commented, that practice reports were that Colt McCoy had some sort of off-season shoulder procedure and he's not getting much(or any) velocity on his passes and they wonder if he'll be ready for game 1. He's 9 of 12 for 42 yards thus far in the preseason.
