Thurman Thomas – 1991
There was a time when running backs had a genuine chance of winning the MVP award. It feels like a long time ago now because quarterbacks dominated the past decade. Thomas had an amazing year in 1991 as Jim Kelly provided the ammunition. Meanwhile, the Bills made it to the Super Bowl but fell agonizingly short of victory.

Nonetheless, this was the best season of Thomas’s decorated career. It was magnificent even by his lofty standards as he led the league in rushing yards. He also won the Offensive Player of the Year award as he set the world alight. That’s why people rightfully regard him as one of the greatest of all time (via SBNation).
