Halftime adjustments. 90 percent of "adjustments " in basketball don't even need a time out . Hand signals designating a defense or offense set are most of the adjustments. Nothing new is taught or learned on the fly. Man, zone, trap , press is all on the fly if necessary. Changing who checks who is easy. The team already knows all the sets and actions ad nauseum. Maybe Hamilton made adjustments at halftime but nothing I'm sure that couldn't been done on almost any possession.
