Four defenders have impressed Bob Stoops

Spring ball is a time for younger players to come into their own. So far, who has impressed Oklahoma head coach Bob Stoops?

"Frank Shannon and Aaron Franklin are doing really well," Stoops said Thursday of the backup linebackers. "They're having great springs. They're going to play. They do a lot of really good things and they've both got great feet, they're tough, they play hard, they're both conscientious, so they're going to play."

Stoops was also high on freshmen defensive tackles Marquis Anderson and Jordan Phillips.

"Jordan Phillips is doing an excellent job,” he said. “Marquis is doing well, too."
