Here's a quote from an ESPN article worrying one of the top, if not the to , who's off all time quoting one of the top, is not the top, coaches of all time, regarding a qb running,
""I was scrambling up the right side, and tried to hold on to the ball, and tried to slide late. The guy hit me and my helmet flew about 10 yards away. It kind of riled up their whole sideline," Brady said. "I remember the next day, Coach Belichick said to me -- I'll never forget this -- he said, 'Hey Brady, if you want to have a career in this league, when you're running like that, you either throw the ball away or slide!' I've kind of taken to that.""
