No he's telling kanter to get the board. Watch it again. Beverly slips in front of Kanter for the board. Jefferson immediately is like wtf
Houston was smart to go at Kanter and pull him out. He is simply not effective out there. Evans and Kanter should have had opposite assignments on that play.

Looks like Jazz were getting back on defense. Whoever was supposed to guard Brooks completely f'ed up. Jefferson points and tells Kanter to cover Brooks. After the play, Jefferson is talking to Kanter, but doesn't look upset.
This early offense play resulted from a bad defensive awareness of Jefferson. He stayed in the middle and searched for Asik. He was the logical assignment for Brooks since Garrett was ion the weakside covering Garcia with no chance for defensive recovery. Burks was in the strong corner guarding Beverly. So it's Jefferson who sunk deep into the zone for no reason while not expecting a body and not being aware that brooks is his assignment with how the transition happened. That forced Kanter to step out.
F'ing Jefferson. No D as always and complaining afterwards.
