Erin Andrews ( @ErinAndrews ) shares her thoughts on what she is most looking forward to in Week 4:
A USC hangover
How will USC respond after its big loss to Stanford? How will the Trojans' depth be tested against a Cal team that gave Ohio State fits a week ago? Will the offensive line play any better? Matt Barkley looked pressured and rushed most of the night vs. the Cardinal. Center Khaled Holmes was missed and his status for Saturday is still up in the air.
Is Notre Dame for real? After taking care of Michigan State last week, rival Michigan comes to South Bend in what should be an epic battle under the lights. Denard Robinson and the Wolverines have won three straight vs. the Irish, who would love nothing more than to keep their undefeated season alive and avenge last season's heartbreaking loss.
State your business
After three straight wins in which Florida State outscored its opponents 176-3, the Seminoles get their first test of the season vs. Clemson at Doak Campbell Stadium. Stopping the Tigers' speedy offensive attack is a challenge in itself. We will learn so much more about how good this 'Noles team is.
Is Oklahoma a national title contender? Another top team finally getting a worthy challenge (from Kansas State at 7 p.m. ET on FOX) plus a week off to prepare for the Wildcats, the Sooners should be ready to go. QB Landry Jones has struggled, will he look any better? How will the defense play with Mike Stoops calling the plays?
Pop culture trend of the week
Psy's Gangnam style -- I'll admit, I'm willing to jump on the bandwagon of the latest craze. Psy's whole thing about his latest dance craze: Dress classy, dance cheesey. And it works.
