I've seen mostly the matchup zone (granted, I'm no expert on these things). The problem is that CO is switching and ending up on the perimeter against a guard at times. DLo being under the basket guarding a big seems to be intentional. Two years ago, Lavin often had Booth down low. I guess a big is supposed to rotate when the entry pass is made. I'm not really comfortable with that strategy but Coach knows what he is doing better than I do.
