The RPI has Kansas up in top 5 I believe, but they played all those games at home and struggled against the South Carolina's and Pacific's. I think they'll fall flat eventually. Plus, they never would have got out of Kentucky with a W on Sunday if Kentucky wasn't ice cold from the field. Tubby starts using the trap earlier, it would have been a different result. But you have to make shots to set up the trap, so ...
As for UNC, the thing that I can't get over is just how athletic they are. It shows more on defense than on offense. They are running and gunning all set up by their defense. But they won't make it through ACC play undefeated just as Illinois won't through Big 10 play either. None of these teams are elite.
FWIW: A buddy sat close to the UNC bench during the Santa Clara lose in the Bay Area before UNC went to Hawaii for the tourney. I called him the next day and was like "How they F--K did they lose that game." He said they got manhandled all over the court and looked lost without Felton. I still don't believe it seeing how Santa Clara has played since, but just goes to show anything can happen ... as we all know.
