Valid points. I just think it's a bit disingenuous to say UNC scheduled two FCS teams when the only reason that quirk happened this year is we've had multiple P5 teams back out after agreeing to home-and-home series with us (Ohio State as mentioned, Tennessee also did this to us a few years back:

Are you telling me UNC's resume would be materially different if, say, we had been able to play Louisiana Lafayette or New Mexico State instead of one of the FCS teams? I feel like it's a straw man argument to artificially depress Carolina's ranking because people want to argue that "their eyes" say Ohio State or Notre Dame or whoever is better because they're "traditional powers."
The fact of the matter is, if we happen to pull off the upset on Saturday night, we'll be a team that has won 12 straight games, beaten the #1 team in the country, and whose only loss was the first game of the season by 4 points in which we had THREE red zone turnovers. You'd have to be willfully ignorant at that point to say we are not playing like one of the best teams in the country.
Anyways, it's clear we're not gonna convince each other, so all we can do is wait for the games to play out and see what happens. Good luck vs. Florida (not that y'all need it).
