A jury of his peers convicted him, and a judge told him he should serve two years for his crimes. He did that. Reinstatement conditions in the NFL have been set for him, and as long as he satisfies those, I'm okay with him playing again.
I have a lot of respect for Tony Dungy, the former head coach of the Colts. He's serving as a mentor and spokesman for Vick's change in character. Dungy believes Vick when he says that he realized he has been doing wrong in the past, and wants to move on with his life. I find it hard to believe that after 2 years in jail, the man still has an urge to do what he did before. Let him make a living again.
