I think you correctly point out that match-ups are key. I will be surprised if Uthoff becomes the primary on Niang, as he has abused oposing bigs that don't have the girth to bang or at least have exceptional length. His outside shooting hasn't proven to be as consistent as last year, so your tradtional centers may be able to guard him with length inside. If Niang is hitting from outside, especially early, that is a game changer as it likely dictates a different rotation for Iowa.
For both Iowa (Marble) and Iowa State (Kane) they have been able to feast with a significant height advantage. I don't know if they will actually be matched up much, but if they are and foul trouble doesnt limit it, this might be the best match-up of the night. Good call on pointing this out as I think it will be a key.
Bold statement.
