For example, some people seem to think that Ohio State's relatively weak schedule (compared to SEC teams) gives them the advantage and makes them the favorite to win the title. According to Dennis Dodd:
What about the fact that they'll almost certainly have to play an SEC team in the championship game?
By virtue of the conference winning the past seven championships, it's almost a lock that there will be an SEC team in the championship game. Honestly, there SHOULD be, based on the continued excellence of their conference.
Even if there are two undefeated teams in the country, a 1-loss SEC champion would still deserve a chance to play for the championship. And if Ohio State (or anyone else) has to play Alabama, or whoever wins the SEC, there's not much of a chance that they'll win, no matter how easy their previous schedule had been.
Keep predicting a non-SEC champion. It's bound to happen someday, so at some point you might be right. But now isn't the time.
