Zion going off was somewhat expected, but what really cooked them was CJ and Alvarado going off from 3 in the first half. Put them in a hole they could never really recover from.
Also, when teams go small against Phoenix, Vogel has to give Thad Young a look. Drewbanks can't do anything on the offensive end against a switch everything defense, whereas Young has good touch around the rim, and is much better at making decisions in the short roll
