College football teams often must replace their leading running back from one season to the next. But usually, they're not trying to replace a guy that's been one of the most productive running backs in school history.

But this coming year, that's precisely what the Utah Utes will attempt to do.

Gone is John White IV, who rushed the ball 534 times over two seasons for 2,560 yards and 23 touchdowns. Both years at Utah he averaged 4.8 yards per carry. During his junior season he carried the team on his 5-foot-8 back, and over two seasons he was a complete back for the Utes.

Now where will the production come from?

Here are four names that are ready to take on the challenge of becoming the next running back at the University of Utah.
