This is based on these assumptions.
CFP rankings - 1.Ga, 2.Mich, 3.TCU, 4.USC, 5.OSU, 6.Bama, 7.Tenn, 8.PSU
Big Ten picking order by school - 1.Mich, 2.OSU, 3.PSU, 4.Purdue, 5.ILL, 6.Iowa, 7.Minn, 8.MD, 9.Wisc
Michigan - CFP- Fiesta Bowl vs TCU
Alternative scenarios- CFP Peach Bowl or NY6 Orange Bowl
OSU - Rose Bowl vs PAC
Alternative Scenerios - CFP Peach vs Georgia
PSU - NY6 Cotton Bowl vs Tulane, Alternative- Rose, Orange or Citrus
Purdue - Citrus Bowl vs SEC, Alternative - Rose or Reliaquest
Illinois - Reliaquest Bowl vs SEC, Alternative - Citrus or Duke's Mayo
Iowa - Duke's Mayo vs. ACC, Alternative - Reliaquest or Music
Minn - Pinstripe vs. ACC, Alternative - Music or Duke's Mayo
MD - Music City Bowl vs SEC, Alternative - Guaranteed Rate or Duke's Mayo
Wisc - Guarunteed Rate vs Big 12, Alternative - Quick Lane or Music
No Big Ten School - Quick Lane vs MAC
MSU, Rut, ind, Neb, NW - No Bowl
Unfortunately Minn gets bumped down to the Pinstripe because it's never been there and MD went in 2021, Wisc in 2018, Iowa in 2017. That means MD gets bumped up to the Music City Bowl or maybe the Duke's Mayo Bowl
There are still a couple of crazy scenerois that could play out like Purdue beating Mich or LSU beating Georgia. Mich and Ga would still most likely make the playoffs but this means giving the Rose to Purdue or the Sugar to LSU whereas if Purdue or LSU lose, they are not getting a NY6 bowl. There is also a slight chance Mich could get bumped to the Orange if it loses. And it's still not clear who would jump into the CFP #4 spot if USC or TCU lose. Would it be OSU or Bama jumping into the playoffs?
One thing is certain. Michigan is not going to the Rose Bowl. If Mich beats Purdue, they will be at least #2 in the playoffs. If Mich loses to Purdue, then Purdue goes to the Rose Bowl.
