Utah is ranked high enough going into the season that if they end up 12-1, they’ll get in. So much of the the rankings come from confirmation bias
I just have a hard time seeing them get in over say a 12-1 Michigan/OSU or a 12-1 OU/Texas. This of course assumes that the other 2 spots go to Clemson and the SEC Champion. And Utah is already ranked behind all 4 of those teams in the preseason coaches poll, using that as a gauge.
