Week 12 was a "gut it out, just get the W" kind of week, with each of the top four teams staring down too-close-for-comfort situations in their respective games.
Because all four won ugly, though, not much, if anything, should change Tuesday at 7 p.m. ET when the College Football Playoff selection committee announces its fourth of six rankings. No. 1 Georgia, No. 2 Ohio State, No. 3 Michigan and No. 4 TCU should hold steady at the top as the nation's only remaining undefeated teams.
The No. 5 spot will be the most interesting, as one-loss USC and two-loss LSU can both make a case to replace Tennessee following the Vols' stunning 63-38 loss to unranked South Carolina on Saturday night.
