Oklahoma has a pair of quality wins over ranked teams and a couple more over teams that, candidly, didn't deserve to be on the same field with OU. You can add a third opponent to that latter pair when the Sooners host lowly Kent State on Saturday.
According to ESPN analytics, there is a 1% chance that Oklahoma will lose to Kent State. With the Red River Rivalry game against Texas dead ahead on the schedule a week from Saturday, it wouldn't be unusual for the Sooners to be looking ahead to that classic confrontation. Even more so while taking on an opponent far inferior to any SEC team, let alone Oklahoma.
