I think he's serviceable at best. Never thought he was much of a QB. Well, that might be a little harsh but he never developed into much. I think Andy's problem is QB. A better QB would be able to make faster reads, get the ball out faster, and make up for O-Line deficiency's. Vick always relied on legs instead of brains. Not saying he's stupid. Just that he just doesn't understand the position like a QB should.
All things considered I think he has had a pretty good career playing QB. He's pretty much done everything that we expect of our QB's except win a SB. He's been an in the pro-bowls, been a finalist for an MVP and has won playoff games. I don't know what more people expect from him. Everyone can't be Manning, Brady, etc. I think Vick has an understanding of the position, but he just goes about it a different way.
