You are making nothing more than assumptions. You are just assuming Michigan would have blown them out. I bet you would have assumed UGA would have blown out Missouri, Vandy, Georgia Tech, Auburn and South Carolina. Did they? No they didn’t.
There are no guaranteed outcomes. That’s why the games are played. What FSU did in the regular season earned them the right to have a chance in the playoffs. Now, is it likely they would lose to Michigan? Yes. But who knows? Harken back to what, 2018 I think? Ohio State was #3 playing unranked Perdue. Guess what? Perdue stomped a mud hole in them. Anything can happen.
You and others who continue to think that FSU didn’t deserve a spot in the playoffs because of this UGA game are just demonstrably wrong. You are advocating punishing a team for having a great season. If the same thing happened to TN, you would be calling the CFP committee a fraud. Which they are.
