Sooners' OL under scrutiny after losing four starters

Posted by ESPN.com's Tim Griffin

IRVING, Texas -- With four new starters from last season, Oklahoma's offensive line is the biggest question coming into the season.

"Obviously, it's a concern because those guys have only played a limited amount," Oklahoma coach Bob Stoops said. "What you want to see is some kind of consistency and how they work through two-a-days and through the season. You're looking for a level of discipline and a level of toughness in how they work."

With only starting tackle Trent Williams returning, Stoops called out the young offensive line for its lack of commitment before spring practice. The group showed some improvement, but Stoops said the offensive line must continue to grow if the Sooners have any hope of an unprecedented four-peat of Big 12 titles.

"This group has a chance to be good. There's potential there," Stoops said. "I don't need to tell you guys what sometimes that can add up to. In the end, that can add up to something really pretty good, or pretty fair depending on how they work and what kind of discipline they have working to get ready."

And Stoops defended his actions when he questioned the group's resolve before the spring.

"I really didn't call them out," Stoops said. "I just get tired of having to compliment guys who haven't done it. In the end, they just need time and we'll see how they've done during the summer and we'll see how we do with 29 practices leading up to the first game.

"I think the ability is there, but it doesn't mean they are going to do it. We'll see if they can play with the consistency to get ready to do that."
