Much has been made about the arrival of heralded freshman running backs Roy Finch and Brennan Clay maybe overshadowing OU's other two young backs, Jonathan Miller and Jermie Calhoun.
But make no mistake, Miller and Calhoun are in the thick of the competition to snag carries behind starter DeMarco Murray.
Miller, a sophomore, says he's 100 percent after spending five months recovering from micro-fracture surgery to repair a torn meniscus he suffered against Texas A&M last season. Before the injury, Miller impressed in limited action averaging 7.2 yards per carry.
"To me he has progressed pretty well and quickly, because sometimes it takes you a while to go through the motions, and you are a little tentative or hesitant on it," said running backs coach Cale Gundy. "He has been out there running pretty fast, and again I think those two young guys (Clay and Finch) have helped him get a lot better in a hurry."
Calhoun, who ran for 220 yards on 45 carries as OU's third back last season, has showed signs already in camp he might be ready for a bigger role.
"He has been really good and comments were made (Sunday) that he looks like a different player," Gundy said. "Jermie has shown a lot of signs of being a great football player. He struggles with being immature at times as a young guy, but that is college life. Again it goes back to when does that light bulb switch on, and he has shown signs of it being on, and he has showed signs of it flickering as well. We need it to be on and stay on the whole time."
Norvell: Young wideouts better be special on special teams
Outside of Kenny Stills, it remains unclear which of OU's other four freshmen wide receivers — Trey Franks, Sheldon McClain, Justin McCay and Joe Powell — will play and which will redshirt.
