As a kid from a small town in Texas, playing football at the University of Tulsa was one of the most exciting opportunities of my life. It also turned out to be the costliest. Football is a dangerous game. When we played, my teammates and I took lot of hard hits — many to the head. At the time, we thought it was just the cost of playing the game. We were never told it was a problem, so we just accepted it. Even today, few players truly understand the risks of football.
