I always thought it would be a natural fit with Shump in the starting lineup and JR being the scoring punch off the bench, but I'm really changing my position on that, for a few reasons:
1) JR is at his best in catch-and-shoot situations. When someone is creating for him, he can focus on what he does best, and he's hit some huge shots in this role.
2) Being on the court with Lebron, Love, Kyrie et al. keeps his bad tendencies in check. He handles the ball rarely and so limits his bad chucking that got him run out of NY.
3) The bench is sorely lacking in ball handling capability. We have Delly (not that great himself) and that's it if JR is on the 2nd unit. JR is not a good ballhandler. Nobody will mistake Shump for Kyrie, but he can at least create some space with his dribble.
4) JR's defense is really not as bad as I expected. He's playing his man pretty well and getting into the passing lanes more than I expected. I thought it would be much worse.
5) The lineup with JR starting is absolutely rolling. We're talking historically-good levels. I'm just not sure there's a compelling reason to change it up beyond the fact that our bunch output is low. But again, I have a feeling the dropoff from the starting unit might be more than what is gained on the bench, solely from a basketball fit standpoint.
I guess I'm not opposed to mixing up the minutes with the starting group between JR and Shump more, but the more I watch the more I'm convinced that JR's best fit with the team is with the guys who are going to create for him.
