I agree with tony. People make mistakes all the time. No one really knows if Vick is truly remorseful, but there really isn't much more he can do other than do his time, apologize, live right, and try and prevent others from making the same mistakes he did.
He might have received the harshest animal cruelty punishment in American history. I say enough already. It's not like he molested someone's kid.
And regarding his ability, he's one of the few football players I would pay to see. Can't really compare him to pocket passers or other mobile QBs. He's a different breed. I doubt we've ever had a QB in the NFL who was also arguably the fastest player in the NFL.
