I don't like early rankings that much either, but you can judge for yourself to some extent just by watching. It's blatantly obvious when it's two mediocre teams playing a close game rather than two good teams playing. And what I saw with KSU against Auburn was two mediocre teams. I would also say that Clemson is not a top 10 team or even 20 team right now, and Florida St. is just jokingly awful.
But Foppa does have a point with how the voting works, and Auburn may very well not drop because of that. But I think they should.
