Guy was a 4 year starter at QB and was never afraid to take off and run the ball.I'm sure he took some brutal shots during those years.
I doubt that when he was playing for the national championship he was worried about his future.
guys and gals in all sports,pro and recreational play and get hurt and try to play again for a title even if it's just a city title.
...trust me I know from experience.I broke a bone in my thumb playing in my city's touch football league.the next week playoffs started and I wanted to play so bad I took the cast off{it was a soft cast} and tried to play....not the smartest thing I've ever done

So I'm just gonna assume Colt was really hurt.
