Colorado no longer has Phillip Lindsay to lean on in the run game, after the second-leading rusher in program history has graduated.
It's also very possible that the Buffaloes' next starter at running back isn't on campus yet. Travon McMillian, a graduate transfer from Virginia Tech, is the favorite to play the lead role this fall.
This is still a big spring for the Buffs at running back, however. As CU begins spring practice on Friday, it will look to the four scholarship backs currently on board to seize an opportunity.
"For all these guys that for the last two years had very limited reps, it's an opportunity for them to all step up or one is going to step up and try to be the guy," running backs coach Darian Hagan said.
