I have to say, I wouldn't be devastated if Roberson took Gbinje's minutes down low. I'm really just not seeing much upside from him, and I think force feeding Roberson some more minutes isn't going to hurt us that much.
Obviously he has to spell Cooney/Ennis, but he shouldn't be playing much point. He just seems to have no instincts at all for the position - or is just too nervous about making a mistake to really play the position well.
I just like Roberson's energy down low - he's a feisty rebounder, and hustles all over. If you can get him to settle down a bit, quit rushing shots, and I think he could still make a little bit of an impact with Baye out. Gbinje is just blah...capable of hitting an occasional three, rebounding a little, but mostly is just a space eater right now. He's so tentative.
