From the tapes I have saw RT seems to project good leadership skills. I have also seen a sense of urgency, something that seemed to be missing from Henne. I agree. I don't want a quiet, shy QB.
From all the reports I have read he is a total "team" guy. Willing to move positions to help the team and put the teams needs ahead of his and his future goals in college. That shows something. He was liked by his teammates, which says something. I don't know if the guy will be a quality NFL QB, but his "make-up" and personality all seem to rate on the high side of what you want out of an NFL starting QB.
