Drop from what? Preseason guesses? That's the danger of preseason rankings, they're not based on this season performance, but people are reluctant to change the preseason guesses even when this season performance doesn't support it.
Miami has shown more this season than ole miss.l and Ohio state. You shouldn't drop ole miss or Ohio state, but I do think they should drop because Miami passes them and we pass them. I prefer to base it on this season more than last season. Don't ignore last season, but preseason guesses should hold much less weight than performance and resume this season. That approach will balance out as good teams play other good teams as the season goes on, but keeping someone high despite someone else having a better resume so far is a bad precedent.
