Education
Clark was a two-time All Big-Eight running back for the Nebraska Cornhuskers from 1986-1989. Following a redshirt season in 1986, Clark played sporadically as a sophomore, appearing in eight games before suffering a knee strain. He rushed for over 1,000 yards in both his junior and senior seasons, and as of 2012, his three-year rushing total of 3,037 yards ranks seventh on Nebraska"s all-time leaders in that category.
He averaged 6.1 yards per carry for his college career.
His career highlight came during his junior season in a 1988 game against Oklahoma State where he outgained eventual Heisman trophy winner Barry Sanders 256 yards to 189 and also scored three touchdowns, the first on a dazzling 73 yard run on Nebraska"s first play from scrimmage.
