DeMarco Murray compiled 774 return yards in 2008, the second-highest total in school history, but played only running back last season following a special-team injury.
"We'll give him an opportunity to return some kicks," said running backs coach Cale Gundy. "It's situations I see and coach (Bob) Stoops sees. The first kick of the game, he's fresh, let him go. Maybe he starts to get a little tired, so we put somebody else in there."
Mossis Madu, OU's leading kickoff returner last season (21.4 yard average), and a few freshmen also are in the mix. Freshman wide receiver Trey Franks ran a 10.1 100 meters at West Orange, Texas.
"He's a fast dude, but he hasn't taken those licks," Gundy said. "We were watching kickoff returns (Sunday), and I was like, 'Holy cow, who is that guy?' They said, 'Coach, he was the fastest kid in Texas.' We're trying to see how quickly we believe (the freshmen) can handle it in a big-time game."
Several freshmen continue to make strong impressions. Stoops said cornerback Aaron Colvin "has been outstanding," linebacker Corey Nelson "has been excellent" and quarterback Blake Bell "continues to do very well."
Stoops said one freshman overlooked is Trey Millard, a tight end/fullback/H-back from Columbia, Mo.
"He's unheralded with this recruiting class because the position isn't a guy who gets the headlines," Stoops said. "But he's probably one of the best athletes we got in this freshman class, his ability to run, his size and strength. He catches the ball great, really fluid.
