That showing against Miami was very impressive. Miami likely isn't as good as we thought, but that doesn't mean Clemson didn't look elite. Its hard to find a flaw in this Clemson team. 
Should be a near-unanimous No. 1. There are problems with this team (pass pro, defending the QB run game), but they're small potatoes in the scheme of things.
I think this is probably the best team in the nation but not sure their resume matches Georgia for quantity of good wins. We'll see if Tennessee and auburn remain good wins. Clemson's blowout win over Miami was very impressive.
