You know that pose Roy takes when the team needs a Defensive STOP and he wants to FIRE them up? He crouches down and yells at them on the Defensive end to get ready. Did anyone see that against Texas? In the past when he did that he often fell to the floor experiencing one of his "blackout" spells. Is it possible that the more intense he gets, the more susceptible to the blackouts he becomes. To which, it is not a stretch to believe that he wants to AVOID those blackouts;therefore, he avoids getting too INTENSE? This game is ALL about INTENSITY. Just a supposition.
