1st half = mostly Mutts, who shut him down while Aluma leaned on Williams in the lane.
2nd half = mostly Aluma, as Banchero switched to the 5 and they had an even quicker guy playing the 4

Aluma is a good post defender, and moves decently well in perimeter defense, but against Banchero he had no chance. Note they didn't bother posting Banchero up, just got him in face-up situations where he could beat Aluma off the dribble. If someone helped, Banchero hit the open guy with a pass.
