I think our best chance out of all 3 is the Ravens. Yes, the Ravens are really good, but we get that game at home. I'm praying we have a snowstorm or something that day to throw Lamar Jackson off his game.
Semi-finals:
Peach Bowl
Fiesta Bowl
Championship: New Orleans (Superdome)
My prediction:
Fiesta Bowl: Ohio st v Georgia (UGA beats LSU in SEC Championship)
Peach Bowl: Clemson v LSU
Championship Ohio St v Clemson
Edit: I switched locations of the semis. The committee wouldnt make OSU play UGA in Atlanta so they would put them in the Fiesta Bowl (Arizona) to avoid the home field advantage for UGA.
