Vick is thought of as a QB, he has attempted over 1,700 passes in the NFL. Everytime the ball is in his hands, the defense will be prepared for the possibility of a pass.
Then assuming the wildcat works (which it seems to so far) he should have an easy time running the ball. They'll adjust start creeping up and passes anyone can make open up.
Our offense doesn't need this gimmick I agree but it's not crazy to add it as well. It just gives defenses more to preprare for.
Its not the worst idea ever, somebody was talking about trading Chris Paul a couple months ago. That makes this only the second worst idea i have heard this year.
