But that's only two ball carriers. Last year West Virginia needed four just to get through the season - Garrison, Buie, Alston and the since-departed Vernard Roberts. And Holgorsen knows he might need just as many this season.
"Running back is probably the hardest position to play in college football. Those guys take a pounding,'' Holgorsen said. "And you ask them to do so many things, from a running the ball standpoint, blocking standpoint, pass protection standpoint, receiving standpoint. So you need a lot of bodies.''
West Virginia has other bodies, of course, but most of those are being worked out as blockers, not runners.
"Ryan Clarke is a guy that can do multiple things for us,'' Holgorsen said. "Donovan Miles has been a bigger guy. Cody Clay has been doing some stuff where he can do some tight end-fullback stuff. We've got quite a few bodies, but we're going to need all of them, that's for sure.''
There is also true freshman D'Vontis Arnold, a walk-on from Miramar, Fla., who stands to be the No. 3 tailback if Garrison doesn't play.
"D'Vontis has done a good job,'' Holgorsen said. "He's relatively unknown at this point, but we do need that body.''
Arnold is only a true freshman, but last season three of the four tailbacks the Mountaineers used were in the same position - Garrison, Buie and Roberts. When Alston missed the first two games of the season still recovering from a neck injury, those were WVU's only tailbacks.
There were supposed to be two more true freshmen in the mix this season, but neither is with the team. Roshard Burney didn't qualify academically and Torry Clayton left school over the weekend after three weeks of practice.
"He said he wanted to go home,'' Holgorsen said.
