Top 5 in the CFP rankings probably won't change this week.
Let's say Clemson and Bama win next week.
1. Clemson
2. Bama
3. OU
4. MSU/Iowa winner
CFP Semis...
Orange: Clemson-MSU/Iowa
Cotton: Bama-OU
Other New Years 6 bowls...
Rose gets Pac12 champ Stanford (assuming they win) and MSU/Iowa loser. Sugar gets an SEC team - runner-up Florida. Houston gets the Group of 5 spot and goes to the Fiesta. That leaves 4 at large spots (Peach, Peach, Sugar, and Fiesta). tOSU, ND, FSU, TCU.
Rose: Stanford-MSU/Iowa
Sugar: Florida-Ohio State
Peach: FSU-ND
Fiesta: TCU-Houston
A Clemson loss changes a lot.
tOSU is highest ranked 1-loss team now. But who have they beat? 1 good win vs. Michigan.
Clemson can argue they should still go in over tOSU with wins over ND and FSU.
But then how do you put Clemson in over UNC with UNC having just beat Clemson and winning ACCCG?
Does a 2-loss Pac12 champ Stanford jump all 3 with wins over ND, USC (twice) and UCLA?
Sugar won't have an at-large spot, it will always be SEC vs. Big 12 in non-semifinal years, so Florida (or whoever they determine is the 2nd highest ranked SEC team) will play the 2nd highest ranked Big 12 team if Oklahoma makes the playoff (either Baylor or Oklahoma State, outside shot at TCU).
