Anyway, I worry very little about polls these days. Midseason polls are vague indicators of something, perhaps letting you know that some team out west is having an apparently good year. I would not have realized Cincinnati was undefeated if I had not taken a quick glance at a poll.
I really can think of no reason to worry about the polls, at any stage of the season. The AP says blah blah and a weekend comes and often the rank ordering shifts because of upsets. There are reasons to criticize the polls of course, and the main reason not to bother is that they do not matter.
At all.
