In 1961, John McKay a spring game between the Trojans and an NFL team composed of former USC players.
Jon Arnett told me he decided not to play and serve as a coach because he thought he might get hurt. He was right. Hal Bedsole, who is in the College Football Hall of Fame, told me he played quarterback for one play and got crunched by Marlin McKeever and Mike Henry.
Two weeks later, Bedsole was in severe pain and an X-ray revealed he had three holes in his stomach. He underwent surgery that night.
McKay never had another game with pro athletes again.
