He made the Chiefs' roster in 1964 as a rookie free agent out of Southern and wound up as the team's second-leading rusher that season with 567 yards and four touchdowns on 105 carries.

Through Hill's inspiration, the Chiefs created the Mack Lee Hill Award, which is given each season to the team's most outstanding rookie.
