Not sure how this happened. Michigan fell one spot this week, from 17 to 18. Meanwhile, Notre Dame leapt from 20 to 11. This doesn't quite add up to me, but I suppose applying logic to this poll will only result in frustration.

Meh. We haven't beat anyone of note yet, a few teams that have jumped us.
