Utah is among four teams leading the nation with 13 interceptions.
That's bad news for normally accurate Southern California quarterback Cody Kessler, who has been picked off twice in back-to-back games for the first time in his career.
The third-ranked Utes can improve to 7-0 on Saturday as they seek to exploit Kessler and a Trojans' passing game that could be missing some key players.
Utah (3-0 Pac-12) owns the nation's second-best turnover margin at plus-12. Safety Marcus Williams has four of the team's interceptions, and cornerback Dominique Hatfield has three.
"We have some guys back there with very good ball skills," coach Kyle Whittingham said.
