Another memorable week of college football, another jumbled resetting atop the polls.

Texas Tech’s incredible win over Texas - if you didn’t stay up late Saturday night to see it, you should question your level of commitment as a fan - sent the Longhorns from the top of the AP poll to No. 5. Alabama climbed to No. 1 (for the first in-season week in 28 years) virtually by default in both the AP and Coaches versions, becoming - already - the fifth team at the top of the heap in 2008. The writers put the Red Raiders at No. 2 and the coaches chose Penn State.

Saturday’s other major result - Florida’s beatdown of Georgia in Jacksonville - shot the Gators up to No. 4 in the AP. And despite falling to No. 5, Texas is still in good position to make the Big 12 title game since unbeaten Tech still has to deal with Oklahoma State (at home) and Oklahoma (in Norman). The Longhorns are by no means out of the national equation.

Things could end up simple enough if, say, Alabama and Penn State were to run the table. Trouble is, the Crimson Tide will find itself immersed in a sea of rabid, embittered Cajuns this weekend at LSU as Nick Saban returns to Baton Rouge for the first time since leaving for the Miami Dolphins after the 2004 season. Note to Tiger fans: What exactly is your issue with Saban, anyway? Were a national title - two, if you count the table he generously set for Les Miles - and two SEC championships not enough for you? Do you still pine for the days of Gerry DiNardo somehow? Curley Hallman, perhaps?

Penn State’s road to Miami looks considerably tamer, but a trip to Iowa this Saturday could be troublesome, followed by home dates with Indiana and Michigan State. And if it comes down to picking an undefeated Penn State or a one-loss Big 12 champion to play for the national title, strength of schedule would certainly not work in the Nittany Lions’ favor, given the paltry status of the Big Ten overall.

If Alabama and Florida make it to Atlanta for the SEC Championship Game unscathed, that battle could well end up being a de facto national semifinal. But that’s weeks - and, unquestionably, several unforeseen twists - from now.

In the meantime, Texas Tech is soaking up its fifteen minutes of fame, and rightfully so. If this season has taught us anything to this point, it’s that the Red Raiders should enjoy it while they can.
