MITCH MUSTAIN ON: On USC's quarterback depth: "It's competitive. I have to improve on everything. I just keep working. Whenever my time comes, I'll be ready...I'm going to keep fighting for it...I don't know why anyone thinks I'd transfer. I said a million times before I came here and since I've been here. I knew the scenario that was possible coming in. I understood the situation. I thought it would be worth it...The hard part of being a backup quarterback is there is no other spot for you. Backup receivers or running backs, they have utility spots they can go do."
Being at USC: "It's so fun at USC. I don't think anybody would trade it for anything. I don't think anyone can match our work ethic. We get the best training. We cherish the opportunities we get...I've enjoyed it. It is better than I envisioned...I enjoy living here."
Sitting out the 2007 season after transferring to USC: "It was good for me to have that transition period and really learn the offense. It was a pretty fast season. By the end of that season, I definitely felt ready to go...I kind of went through that phase where you're just having to tear everything down and start over again. I'm finally through that."
Why he left Arkansas: "It just got to the point where I knew it wasn't going to work out there...It was a unique experience, but it was a great learning experience...I was trying to get away from the perception of being 'the guy' and the expectations that were placed. It's a little bit different game here at USC as far as the expectations. They come a little bit later once you've earned your spot. That's something I was looking for...It's so big here in Los Angeles. You can kind of go your own way."
WHAT OTHERS SAY: Former USC quarterback Mark Sanchez: "He has a great arm. He can throw the ball through a brick wall. And his experience at Arkansas will really help him."
