This could be great or a total bust. Henson has great talent and excelled in a skills exhibit earlier this year. The doubt that I have is in his dedication and toughness. He did give up football to play the game he loves, then quits that once he doesn't get immediate results. If he can't dedicate himself to the game he loves, how will he do with the game he doesn't love? Also it seems to me that he left football, in part, because he didn't like the physicality of it. Translation: he didn't like to get hit.
He may lack the mental and physical toughness to excel at football. I hope I'm wrong because he does have great skills, but then again since he's playing for the Cowboys he couldn't suck bad enough.
