Well I do think they (GM, Trainer, Etc.) not so much Gentry were over Zion's mins so it is to keep Zion healthy overall so we can have him longer. He did look pretty winded.Zion goes off in the 4th and Gentry takes him out of the game. Just another reason the Pelicans need a new coach.
But since Gentry had kept him in longer than necessary he should have made an executive decision and just kept him in. It's like dude, coach your team.
