James Nathaniel Brown was an American football fullback, civil rights activist, and actor. He played for the Cleveland Browns of the National Football League (NFL) from 1957 through 1965. Considered one of the greatest running backs of all time, as well as one of the greatest players in NFL history, Brown was a Pro Bowl invitee every season he was in the league, was recognized as the AP NFL Most Valuable Player three times, and won an NFL championship with the Browns in 1964. He led the league in rushing yards in eight out of his nine seasons, and by the time he retired, he held most major rushing records. In 2002, he was named by The Sporting News as the greatest professional football player ever.

A fullback (FB) is a position in the offensive backfield in gridiron football and is one of the two running back positions along with the halfback. Fullbacks are typically larger than halfbacks, and, in most offensive schemes, the fullback's duties are split among power running, pass catching, and blocking for both the quarterback and the other running back.
