A game involving winless Arizona shouldn't have a total this high. The Wildcats rank 127th in scoring at a meager 14.3 points a game. The Under has cashed in Arizona's last three games, winning by an average of more than 10 points under the total.

The Wildcats, though, haven't quit on defense. They held Washington to seven points in the fourth quarter last week before losing, 21-16.

Mistake-prone USC is in disarray. The Trojans have an interim coach and morale issues. They are averaging 21 points their last two games, losses to Notre Dame and Utah.

USC QB Kedon Slovis entered this season highly-rated. But Slovis has put up mediocre numbers with a 9-to-6 TD-to-interception ratio.
