Ron Dayne is one of the best college running backs of all time. As a four-year starter at Wisconsin, the "Dayne Train" set the NCAA Division I-A rushing record for total yards in a career.
He gained 1,863 yards as a freshman, 1,421 as a sophomore, 1,325 as a junior, and 1,834 as a senior. That same year, 1999, he won the Heisman Trophy. His rushing record still stands to this day.
He made this list simply because he had no production as an NFL running back, not because he was an awful player. He showed the power he dominated defenders with in college, but gained weight and had no athleticism. He was about as one-dimensional as you could get, and took quite a pounding.
Dayne was selected with the 11th overall pick of the 2000 NFL Draft by the New York Giants. Over his seven-season career, he never once ran for 1,000 yards or scored 10 touchdowns.
He carried the ball 983 times for 3,722 yards and 28 touchdowns. Dayne still hasn't officially retired, but hasn't seen any action since 2007 with the Houston Texans.
