Listen, if Lane Kiffin held back against UCLA, then he is an idiot.
I don't think he's an idiot. He wanted to win that game. When you are rebuilding a program, you don't just mail it in one week during a major OOC game on national television with the hopes that you'll hide enough of your real scheme so that you might have a snowball's chance in hell at beating your main divisional rival on the road.
Lane Kiffin wanted that game and he did everything he could to win. The defense did everything it could to win. They blitzed from all over the field, moved Eric berry all over the place, and did everything they could after the debacle a 3rd quarter to win that one.
