In order to clean up your handle on the Arizona Wildcats, we're breaking down the roster position by position. So far, we've discussed special teams,linebackers, wide receivers, the secondary, the offensive line, defensive line, and the quarterbacks. Last but not least, we turn the attention to the deepest and most versatile group. It's Ka'Deem Carey and the running backs.

Key returners: Ka'Deem Carey, Daniel Jenkins, Taimi Tutogi

Key losses: Keola Antolin, Greg Nwoko (moved to defense)

The zone read offense of Rich Rodriguez asks for the Arizona Wildcats to have more than one option at the running back position. Luckily, that's one of the few things an anemically-recruited roster does have.

UA has depth with Ka'Deem Carey, Daniel Jenkins, Kylan Butler and Taimi Tutogi, but when you look at those names, it's the versatility that sticks out.

Jenkins and Butler give the Wildcats small, shifty backs to hide behind the offensive line, but it's Tutogi and Carey who could become stars.
