The 1978 Heisman Trophy winner while a Junior at the University of Oklahoma, Billy was the National Football League Offensive Rookie of the Year in 1980 leading the league with 13 rushing touchdowns. He played five seasons with the Detroit Lions and became their all-time leading rusher before a devastating knee injury cut his career short (he ranks second on the all-time franchise list today behind only Barry Sanders). Billy Sims turns 71 today.
