Lane Kiffin wasn't impressed about Southern California's No. 14 ranking in The Associated Press' preseason poll.

After the Trojans committed six turnovers during a three-hour scrimmage Saturday, the first-year coach was worried about his team's miscues.

''I have zero concern of where we get ranked in the poll,'' Kiffin said. ''We haven't won a game yet. We've done nothing, so that's completely meaningless.''

Incumbent starting quarterback Matt Barkley completed 13 of 29 passes for 173 yards and two touchdowns, but threw an interception. Backup Mitch Mustain was 14 of 27 for 181 yards and two touchdowns along with two interceptions.

''We've got a lot of stuff to clean up, we're going to have to execute better,'' Mustain said.
