I'll explain how Wisconsin keeps it close. The frontcourt of Wisconsin is extremely versatile. Kaminsky, Dekker, and Hayes can all play very well inside and outside. If they are to keep this close, Gasser and Koenig need to play pick and roll with Kaminsky and Dekker in order to get WCS/Towns/Johnson on the move. Gasser are Koenig are good 3-pt shooters so we'll see how Cal handles them. Do they go over the top of the screen and risk Kaminsky or Dekker rolling to the basket or do they go under and leave Gasser/Koenig open for a 3? Also, whoever of FK and SD that isn't involved in the P/R will have an easier time of posting up while the bigs of UK can't set their feet and get you off the block. Hayes can be used as a chess piece of sorts as he'll have a slower Lyles on him and can take him off the dribble or run him off some screens.
They'll have to knock down shots at a similar clip as yesterday. Dekker is playing right now like a 1st team AA. With him and Kaminsky playing like they did against Arizona, they have a fighting chance. But, others will have to step up and knock down shots when they get the chance and they won't have many chances. FK and SD took 31 of the 45 FGA yesterday so even though chances will be slim players like Hayes, Gasser, Koenig need to be extremely focused and ready to go.
Defensively, they need to build walls and not let the Harrisons and Ulies abuse them like Arizona did yesterday. You have to make UK beat you over the top with the 3-point shot. If I were Bo Ryan, I'd play a packed in 2-3 zone.
