I believe that this would be a horrible move.
It is my opinion that Marcus Vick is how he is, in no small part, because of who his brother is. Not saying it's Michael Vicks fault but I am saying that Marcus acts out because he probably hears nothing but "Your Brother Mike" this and "Your Brother Mike" that. It seems like he struggles to do anything to seperate himself. If this is indeed true, it would be a difficult situation for both he and Mike in Atlanta. Secondly, what happens to Marcus if he starts to develope? How does he assurt himself? How does he gain playing time? He won't develope the way he should if he goes to another team. How could he? Thirdly, what happens if the Falcons have to cut him after a couple of years or have to take disciplinary action with him? What happens if Mike takes issue? Then, the club has a problem with there star over his little brother who may not deserve the roster spot in the clubs opinion.
I just wouldn't like it.
