Ohio State is currently 7-0, has played a complete crap schedule, and is ranked #1 in all the human polls.
Boston College is currently 7-0, has played a complete crap schedule, and is ranked #2/3 in the human polls.
Arizona State is currently 7-0, has played a complete crap schedule, and is ranked #12 in the human polls.
The only reason ASU is stuck at #12 is because Ohio State, BC and other teams started the season ranked higher than Arizona State. Now the preseason rankings are usually based on the previous season's rankings and some vague guesses the voters make about the returning players on each team. In other word, there's basically zero relevant information in the preseason polls. But because voters tend to follow an algorithm of maintaining the relative ranking of teams until they lose, Arizona State has a mountain to climb if it wants to reach the alleged "national championship game".
Given that 12 games clearly isn't enough to distinguish between the top 8-16 teams in the nation, and given that voters are typically morons, it amazes me that this information is used to determine a 2-team playoff for college football's national championship.
