If Oregon is ranked top 5 pre-season, I think we end up getting more than enough token votes to actually fall higher (i.e. lower number) than 25. Even if they're top 10 to start the season, I think this is a possibility.
What would be a little crazy is if Oregon then goes on to defeat tOSU the next week. And both Oregon and tOSU finish the regular season without any other losses. And then we continue the year undefeated, blowing out the competition through another championship. We'd be crazy high in the computers, and I'd have to think we keep getting AP votes to stay in the top 25. Maybe even some real Heisman buzz for Lance.
Oh... that also means we'd have the longest D-I winning streak in history, surpassing Oklahoma. We'd also have roughly a top-3 active win streak against FBS foes.
Okay... some of this might be a little far-fetched. (Or is it???)
