I don't think there is much to discuss, the guy is a solid player and it is nice to see him get back on the field and turn his career around.
In College, most people said that one of his strongest attributes was how he kept his composure whether the team was winning or losing, so it was a little shocking to see him go downhill mentally last year.
I think something very serious happened in his life and like most of us, had a hard time dealing with it and it set him back.
Funny that he was replaced by a guy (Kerry Collins) who had a "setback" in his life and kind of quit while in Carolina but resurrected his career in New York.
Since Vince Young is a Texan, I am going to root for him and hope he does well.
