Aundrey Walker, USC's next left tackle

It seems like Aundrey Walker is going to be USC's starting left tackle in 2012.

The 6-6, 320-pounder hasn't had a perfect go at it since moving to the blind side eight practices ago, but he's been good enough to give Lane Kiffin confidence to leave him there long-term.

"He just fits better over there," Kiffin said on Thursday when asked about Walker's status. "His length and his size, when you look at left tackles that's what they look like.

"So hopefully we can work through it, he can get used to it over there and play better over there."

Walker, of course, lost out on the left-guard job last fall as a true freshman and then started the spring as the right tackle before switching with Kevin Graf a week into it. Now, with Graf performing well on the right side -- where he started all 12 games last season -- Kiffin said Walker would be his left tackle if the Trojans played a game tomorrow.

But will he for sure be it when they play their first game Sept. 1? Will Graf be allowed to challenge him again in fall camp?

"That I don't know," Kiffin said. "We'll look at the whole spring after the 15th practice and put it all together in the cut-ups and look at it.

"It's looking that direction because Kevin played better (at right tackle), too."

Walker was always looked at as the Trojans' future left tackle -- it was just a matter of when, as in this season or when Graf leaves after this season or the next one.

It seems like the process has officially been sped up.
