Last year, the secondary had 22 interceptions, which was twice as many interceptions as Utah's opponents. The secondary returns five excellent starters: Senior CB Reggie Porter (38 tackles, 11 break-ups); senior CB Dominique Hatfield (33 tackles, 4 INTs); senior nickel back Justin Thomas (48 tackles, 3 INTs); junior S Marcus Williams (66 tackles, 5 INTs); sophomore safety Chase Hansen (17 tackles, 1 forced fumble). The back-ups are pretty good, too, and have some playing experience.
I took that information from this article:

The D-line. Just monstrous. And consider that one of our D-line transferred to USC so that he could get more playing time (granted USC is thin there this year). Here's an article about the Ute D-line:

The linebackers present a question, but there is talent there to be exploited.
I expect a stout run defense, and plenty of turnovers. The turnover differential was huge for Utah last year, and made up for some of the statistical weakness of Utah's pass defense.
