Week 9 college football picks: USC vs. Arizona

The computer is siding comfortably with the visiting team, as USC has the outsized 88.7 percent chance to defeat Arizona this weekend.

That leaves the Wildcats an 11.3 percent shot to hand the Trojans their second loss of the season and move to .500 in the record books themselves.

The oddsmakers are going with the road team, as USC comes in the 15 point favorites to defeat Arizona, according to the lines at SI Sportsbook, which set the over/under mark at 75.5 points for the matchup.

USC sits at No. 10 overall on the index's 131 college football rankings, projected to win 10.5 games this season and be 15.9 points better than an average team on a neutral field, according to the computers.

That adds up to a 32.7 percent shot to win the Pac-12, the best mark in the conference, and a 9.9 percent chance to make the College Football Playoff.

Arizona checks in at No. 83 nationally on the FPI rankings, second to last in the Pac-12, and estimated to be 4.0 points worse than an average team, while expected to win 4.2 games this season, according to the metrics.
