They have zero big wins and a bad loss. Their strength of schedule is also pretty bad, especially compared to the teams actually in the hunt. A lot of teams would have to lose for them to be considered and only after a solid beating of Oregon.
I think three SEC teams get in ahead of them.
Oregon actually has an outside shot if they get some unlikely help. A close loss on a “neutral” site to the 5th best SEC team is all they have. A lot would have to happen to help them get in. They are realistically Barely in the top 10, let alone top 4. From a head to head perspective and on a neutral site, they would lose to the top 5 teams of the SEC, the top 2 teams of the BIG10, and Clemson and Oklahoma.
If you watch much football, the PAC is truly behind the rest and their record shows it.
