I am going to beat my personal dead horse but I think CJP really has to look at how he sets up Mose's role. It is really hard to run a 4 out offense and then tell Moses he can't shoot beyond 15 feet. It destroys the spacing and it is hard to put a kid 20 feet from the basket - throw him the ball there - and then expect him to do something without shooting. It doesn't work.
They ran Moses in a 3 out system a couple of games ago which kept him 15 feet or so from the basket and thus in a role where he could make plays. They haven't gone back to it since and Moses has suffered despite starting. If you want his help on D where his length and athleticism are real assets, then you have to put him in an offensive system that allows him to do at least OK. I understand the issues of having a separate system just for one player and this does restrict the space available for Banks. But it is a tradeoff that has to come if you are going to play him and get his D.
