Charles White
As a senior in USC, Charles White was the Heisman Trophy recipient in 1979. After the big win, the Cleveland Browns picked him during the first round of the draft. He disappointed his coaches and fans for the next four years. After all, he rushed for only 942 yards. After he left the team, he signed a contract with the Los Angeles Rams but only rushed once in the league. Once he retired from the NFL, he decided to compete in American Gladiators and won during both of his appearances.
Billy Sims
Isn’t it sad when an injury derails a promising career? Billy Sims had been in the NFL for five great seasons when he blew out a knee. It pretty much ended his career. If he had been alive in this day and age, he could have recovered with modern medicine. The Detroit Lions drafted him, which was a great idea as he breathed new life into the team for five seasons. He reached the Pro Bowl thrice and led the team to the playoffs two times. At the time of his retirement, he had 42 touchdowns and 5,106 yards.
