As for me personally, I like VY. When he helped win a national championship, I was in a room where all the participants agreed to name their next child Vince Young, whether it was a girl or a boy. Yes, there was some drinking going on. For those who know my history, I was one of the biggest (rational)VY supporters on the MB, though, as with any player, I noted his good and bad points.
I have watched a lot of sidelines from the seats, and have never seen someone so anti-social as VY during that game. Andre Johnson usually stands next to someone at least, or isn't standing 30 yards away from his closest teammate.
May be nothing. May be something. I have to say that though I am not as nitpicking as some with the way that VY carries himself, I've seen a few things in the what he says and does that give me a little concern.
