Problem is this is chess not checkers. Look 2 moves ahead. Oklahoma now has 3 top 25 opponents in the last 4 games. Gophers have 3 ranked including 1 higher ranked. Utah and Oregon have each other. Georgia and Alabama are interchangeable based on the SEC championship game. The PAC 12 champ will need help to finish any higher than 5 with the games left in play based on the rankings.
Also, as much as it sucks to say, I am convinced the Utes would have been at 6 in the initial rankings had they beat SC and would have still been at 6 this week behind a 1 loss Alabama.
