Here is an article discussing Mike D'Antoni's offense. It's discussion of how the screen and roll can work to create offensive opportunities. It is very useful in understanding how Michigan uses the screen and roll, usually with Morris and Morgan, and in understanding how perimeter spacing is intimately related to how the screen and roll is supposed to work.
I think that, as the team gets more experience, it will come much closer to the "Seven Seconds or Less" approach that D'Antoni is famous for. When the screen and roll works more consistently, you won't see as much dribbling from Morris or as much perimeter passing leading to desperation three-pointers.
I know it's unlikely, but I hope that spreading an understanding of the principles about floor-spacing and the screen and roll will reduce the number of people who say ignorant things about Michigan's "three-point offense."
