Earl Campbell – 1979
Campbell’s seminal year came in 1979 when he outshone his fellow running backs. He played for the Houston Oilers and emerged as one of the best players in the NFL. Furthermore, fans will never forget his MVP-winning season as he led the league in rushing yards and touchdowns (via NFL.com).

He only won a single MVP award but he was a three-time Offensive Player of the Year. Campbell posed a dangerous threat to opposition teams who struggled to deal with his power and tenacity. The running back put his body on the line during games as he showed no fear on the playing field.
