Iowa had 2, both on the road. Wisconsin was 19 when they played and Northwestern was 20. Wisconsin has dropped out, but NW is at 17. Nobody cares about where teams were ranked at the team barring injuries tanking a team's season. But yes, Iowa has zero losses and destroyed a higher ranked team on the road. ND has 2 top 25 wins, and their 1 loss is to undefeated #1. MSU has 3, though their 1 loss it to a bad Nebraska team. Oklahoma has 2, though their 1 loss is to a bad Texas team Baylor has 1, with a better loss. OKSt has 1, with a better loss. Stanford has 2, but has 2 top 25 losses to go with it. Of course schedule goes deeper than top 25, but "hey we beat some fringe top 25 teams (and lost to 1)" gets you first place votes and unquestioned status as top 1 loss team? After next week, they'll either have 2 top 25 wins, and 1 loss to an unranked team, or they'll be 1-1 vs. the top 25. At least Ohio State was defending national champion, Bama is just "well they have a lot of talent"
