Why does Stotts continue to play Meyers over Vonleh? The only logical answer is that Neil's trying to showcase him. Otherwise, it makes no sense.
For all the narrative that's out there about Meyers "being a shooter", it's simply untrue. He passed up a WIDE OPEN look late in the 4th from 3 because he was so ice cold. He's also not really that good defending bigger centers. He got that rep for playing Boogie Cousins tough one game last year in Portland, but nearly every other time since, he hasn't been that stopper in the low post.
Vonleh is a better perimeter defender, rebounder, and he can finish around the rim.
