The three most important qualities for Andy are: character, character, and character. He's got enough physical tools matched with great experience and intelligence that you'd trust him with the keys to your football team.
Is there anyone who doubts that Andy would give excellent effort at preparation or at learning an offensive system? A lot of the other guys seem flaky to me.
Gabbert and Locker don't seem flaky to me, but Mallet and Cam do.
Locker has issues with accuracy, and as great of a talent as his arm is, I don't think a team should take a 1st round chance on him. The bust potential is strong with him.
Cam is a dunce, and though his upside is a more athletic Big Ben (which would be phenomenal), I don't see him as intelligent enough to run a pro style offense. The NFL players are all stronger and faster, and won't have issues catching up to him and laying the hurt. If he can't develop more pocket presence, and use his feet to escape rushes and buy time, he'll be another JaMarcus Russell.
Mallet needs to lay off the coke and quit doing a really good Ryan Leaf impression, or he'll have warrants out for his arrest in no time.
Gabbert I don't know enough about to comment on, so I won't.
But a team at the end of the 1st/early 2nd would be foolish to look over Andy. His ceiling isn't as high as some of the others, but his floor is MUCH higher than them. Good value.
