Carl Weathers
As you might expect from the actor who played Apollo Creed, Carl Weathers was quite the athletic star back in high school and college. At St. Augustine High School, he earned a scholarship for his athleticism and astounding performances in boxing, football, wrestling, and an assortment of other sports.
He continued playing football for Long Beach City College, but an ankle injury cut his career short. Carl caught a semi-break when he signed with the Oakland Raiders, but he moved to Canada to play for the B.C. Lions after just one season. After that, he lost by way of knockout to Rocky.
