It's still kind of a weird time for rankings. Is Ohio State really the number 4 team in the nation? Probably not, but they haven't lost and so many above (Louisville, Texas, Iowa) have lost to lower ranked teams or haven't really been challenged but were ranked higher (Iowa St., Notre Dame, UNC). Granted, based on the results of Tennessee since that game, they weren't as big of a challenge as early pundits assumed.
Kind of weird that UCLA is now ranked 20th at 5-0 (notable wins over SDSU and Tennessee) but Marquette isn't ranked at 5-0 (notable wins over Texas and Gonzaga). Probably the P5 bias there.
