I think it's also important to look at the point margin in those games. ISU has blown out its opponents it has beaten, none have really been a close game.
ISU passes the eye test and still has to talented players to integrate and raise the ceiling of the this Cyclones team potential. They move the ball like a seasoned team on offense and I haven't seen ISU have this much defense potential since the Estauschy years. Very nice surprise from a young team missing 4 contributors.
Iowa hasn't looked that much different from last years team to my eyes (slow guard play, turnovers and poor defense rotations resulting in open 3 and layups). Oregon and PITT games in particular showed a lot of those issues but neither team took advantage by hitting the 3's and missing layups resulting in wins.
