Two of the 3 are the ONLY FBS teams ranked in Sagarin's top 60 who haven't even played a SINGLE game against the top 34. Their respective SOS ranks are 81st and 145th. They are ranked 8th and 25th in the CFP rankings.
The third is the ONLY team in the country that has 4 wins in Sagarin's top 34. Their SOS rank is 41st. They are the undefeated leader of the second-best rated conference in Sagarin.
And they are ranked BEHIND one of the teams in the first group despite being AHEAD of them in the AP rankings the ENTIRE season until last week.
I agree that if Michigan had Indiana's resume, they'd be ranked in the top 5 easily.
But, if BYU had Indiana's resume, they'd be ranked OUTSIDE the top 12 as we saw in 2020.
