That's would be serial killer cold if OSU gets in with one loss and Oregon doesn't.
Polls are always wacky with crap like that. I would argue OSU is playing better right now and their QB situation has been resolved.
While that makes sense on paper, it leaves out Oregon beating OSU at their place. Sure you can say OSU is playing better ball, but that would be an absolute slap in the face to Oregon if OSU got in with one loss and Oregon only had one as well.
