There's likely a very simple reason for him not being in at those times and for his limited minutes- he's not showing it in practice. There are obviously other guys on the team team at his position that are showing the staff that they deserve those minutes. Nobody is replacing Tribble, Scott's a better defender and Thornton far better distributor. Tavari is certainly the most explosive of the bunch and I like the kid but Groce will put whoever he thinks is best in the moment in the game. Also, I wouldn't put too much on a 42 shot sample size. That's two more than Enrique.
