He was known as Sweetness and after his death in 1999, the NFL's Man of the Year award - given to one player each season for their volunteer and charity work - was named in his honor.
He married Connie Payton in 1976. His son Jarrett played running back at the University of Miami. Walter also had a daughter named Brittney.
He broke the record of most NFL rushing yards, which was formerly held by O.J. Simpson.
