Usually JB goes 3 guards, but with BJ Gbinije we don't know what postion they will play. And with Patterson, Gbinije, CJ, Dajaun and Ennis all able to attack off the dribble, and with Rons defense, I don't think JB should or will hold either back.
At worst case Ron could be a isolation clone of Brandon Triche if he doesn't make his three point attempts. I do think hes alittle faster though, and his midrange shot can fadeaway and is less arm and more hands in his release which bodes well. Maybe he will be able to back down his defender at a slower pace. Brandon was good at that but had a hard time shooting once he did and opted more for attacking the low post.
I think JB will be high on Cooney and he will atleast play 15 minutes. That being said no worries.
