While most of the Big 12 spent the past 20 years slinging the ball through the air—and yes, Kansas had one of the greats at doing that, too—the Jayhawks have been stronger on the ground. During many of the non-Todd-Reesing years, the running back has been KU’s most dynamic offensive player (Steven Sims Jr. being an exception).
To that point, Kansas has had 12 backs rush for more than 2,000 yards for their career. Five of them started their career after 2000. If you look at the top 12 receivers in terms of receiving yards, six of them started their careers after 2000, but three of those had the benefit of playing with Reesing (only Jake Sharp can say that from a running back perspective).
