You're a complete idiot.
Mike Vick has potential, VY is a leader and Marcus has 5 turnovers?
First of all, his name is Marcus, not Mike. Mike is his brother, please, if you can't separate them, please, don't participate.
You want to know what separates VY from Marcus? VY tucks the ball, and if the reciever isn't completely open he will run it. Marcus will throw it first, with way better touch, after only starting 9 games in his career, and if it isn't there, he will move.
Now you can stick to whatever ESPN tells you, or you can actually watch the games.
