I see Oregon dropping to around 8th or 9th, just ahead of Michigan State. Arizona SHOULD jump to top 15. Consider all of the top 20 matchups this week that could influence the rankings.
Alabama @ Ole Miss = Bama most likely takes care of business, Ole Miss drops out of top 15 (at least)
LSU @ Auburn = LSU loses, drops out of top 20. Auburn loses, should drop to between 12-15.
Stanford @ Notre Dame = Stanford win will jump them into the top 10 and Notre Dame out of top 15. Notre Dame win could put them in the top 5 with enough things going their way.
Nebraska @ Michigan State = Michigan State win SHOULD put them in the top 8 EASY. With a loss, they could fall out of the top 20. Nebraska wins and jumps into top 15.
Texas A&M @ Mississippi State = A&M win, puts them into top 5. With a loss they drop out of top 10 and Mississippi state jumps into top 10 with a win and out of top 20 with a loss.
Tons of opportunities this weekend. If Ohio State can handle business easily, maybe some parody across the nation this weekend could help them out.
