Green, Mustain add a touch of Arkansas to scrimmage

USC’s second scrimmage of training camp was infused with a heavy dose of Arkansas flavor Thursday night.

Running back Broderick Green, a freshman from Little Rock, and quarterback Mitch Mustain, a transfer from Arkansas, both made big impressions during the 78-play scrimmage at the Coliseum.

Green, a 6-foot-1, 230-pound tailback, gained 54 yards in seven carries and scored on a three-yard run in a style reminiscent of LenDale White.

“He’s a horse, dude. That guy trucks,” said quarterback John David Booty, who passed for three touchdowns. “It’s amazing to watch him run. You think he’s going to be down and he just keeps going and going. We’re expecting big things from him.”

Coach Pete Carroll also liked what he saw from Green, who is being allowed to practice while awaiting academic certification from the NCAA Clearinghouse.

“He was hard to tackle, he did well in the open field and he ran over a couple guys,” Carroll said.

Mustain, who is a redshirt, completed all three of his passes for 54 yards, including a 12-yard touchdown to freshman fullback Jordan Campbell.

“I wasn’t sure when I was going to get in, but I figured I would and it worked out great,” said Mustain, who is expected to battle Mark Sanchez for a starting role in spring practice. Sanchez did not participate in the scrimmage because of a broken thumb.

Mustain started eight games as a freshman at Arkansas last season.

“He’s been shaky with the limited amount of reps he had, but when he got on this playing field he looked like he was in control,” Carroll said.

Booty completed 11 of 17 passes for 173 yards. He threw two touchdown passes to Patrick Turner and one to Fred Davis. Aaron Corp was four for nine for 42 yards with an interception. Michael McDonald was one for five for nine yards. . . . Allen Bradford ran for 27 yards in five carries. . . . Tackle Drew Radovich, who has been out because of a back injury, said he would participate in some contact drills today.
