College football rankings, Week 15: Sagarin BCS doesn't give NIU, Boise State a chance

The BCS' six computer ranking systems will combine to decide one third of the final, official BCS rankings on Sunday night. So far, the only one publicly available is Jeff Sagarin's ELO CHESS system, which eliminates margin of victory from his much better, actual rankings, according with the BCS' very silly rules.

There are no surprises at the top, with Florida's very strong computer ratings continuing to give it the advantage over Georgia it might end up needing in order to ensure itself of a No. 3 BCS spot and thus a Sugar Bowl bid. The Dawgs remain far back, at No. 9, and look like they'd need an overwhelming show of support from the two human polls in order to get into the BCS -- not likely.

There's little drama here anywhere else except for the middle of the rankings. Northern Illinois, the team looking to finish No. 16 in the full rankings, gets no help from Sagarin, ranking outside the top 25*, just like last week, this time at No. 32. Boise State ranks No. 43, and no other non-AQs has a chance of crashing the BCS. Both good pieces of news for Oklahoma fans, as their team appears to be the one very likely to take that final BCS spot if NIU can't go.

* Only top 25 computer rankings count toward the BCS.
