My Cowboy candidate has got to be Bullett Bob Hayes who was brought in as a sprinter and became a wide receiver and changed the game forever. Read about mr. revolution below http://tracking.si.com/2014/06/20/michael-vick-i-revolutionized-the-game/ And my comment to him is that yeah, he did revolutionize the NFL by being a criminal/felon/inmate and halfing a crazy no-talent brother who revolutionized tweeting with sour grapes messages. Other cowboys besides Hayes who come to mind is the Landry/Brandt/Schram troika who began using computers to recognized talent. That truly revolutionized NFL football. What half you got, mens and womans? EDIT: Thread title edited by staff.
