I don't know how good of a team Creighton is, but I do agree with your first statement.
The NIT would be a dream season for Iowa, lets face it...my expectation this season has and always will be to finish somewhere above .500, or a game or two below .500.
Heading into this season, I thought the play of Basabe would really have a lot to do with it, but so far it still comes down to Iowa being able to defend. It is understandable that a team gets hot, but Iowa has to do something to break it, get in the face, don't help and make them beat you off the dribble...double teaming on teams that have shooters everywhere is asking for a nightmare. There are times when convention just doesn't work and that is why mid-majors have success against Power six teams, because making "basketball sense" doesn't make sense against them.
Mid-majors have the success because they dictate what happens in the game and today is no different. I am not ripping on those players, but there is a reason they aren't in power six leagues...those weaknesses have to be exposed.
