PLAYER TO WATCH

Utah:

CB Clark Phillips III. He leads the Pac-12 with six interceptions and is the first Ute since Robert Johnson in 2009 to pick off that many passes. Phillips, who also has five pass breakups, is dangerous when he gets the ball in his hands. He has returned four of his nine career interceptions for touchdowns.

USC:

QB Caleb Williams. Who else? He's the frontrunner to win the Heisman Trophy, with 44 touchdowns (passing and rushing) to just three interceptions. Williams was spectacular Saturday against Notre Dame, his 19-yard scramble immediately going viral and becoming the defining moment of his Heisman candidacy.
