With 21 tackles and three sacks last season, Texas Longhorns defensive tackle Kheeston Randall is the lone player at the position back with any siginificant experience.
And coach Mack Brown didn't sugarcoat what he needs from the 6-foot-5, 295-pound junior from Beaumont.
"It's our true key on defense," Brown said. "He needs to step up and play like Roy Miller and like Lamarr Houston from last year. we've got numbers at that position, but we do not have quality experience. We have to look at look at a number of guys to see what fits."
Brown said he has the option of going to a 3-4 scheme and moving defensive end Sam Acho in, but Brown said he'd prefer not to go that route.
"All of a sudden you're looking at Calvin Howell, Tyrell Higgins, Kyle Kriegel," Brown said. "You're looking at freshmen. That's one of the keys for us to determine in preseason."
