I think USC losing hurts ND much more then Oregon. Say USC doesn't get to the Pac 12 title game its like UCLA would be the team replacing them. UCLA plays 3 of their last 4 at home with their only road game against WSU. They would likely be ranked top 20 by then at least. USC loses to other Pac 12 teams will hurt ND in the computers while they shouldn't hurt Oregon much if at all. The Ducks are probably very big Arizona fans at the moment. 49-0 over a possibly ranked team at the end of the year would look pretty good to alot of pollsters.
Hoke was top notch at this aspect of his job.
