IMO those are all great matchups for Michigan - except for Teske on Morgan.
If Juwan gets hot from outside (Butler), Teske will be forced to go out to guard him. That opens up things for RL , Al or DG to drive; or, if JM takes him off the dribble, we could get good looks from other defenders dropping off to help.
Reason I play CM on Juwan? As you said, he’s their best defender. He’s quick, has length, and while he doesn’t have Morgan’s bulk he’s stronger than most realize. My nightmare is CM beating Juwan to the spot defensively and picking up charging calls on him - exactly what cannot happen if we hope to have any chance.
