In my humble (cough cough) opinion, there are two players that bring acidity up into my mouth when they come into the game, and unfortunately, they always come in together. Joseph and Whiteside. Joseph has the worse plus/minus on the team, and is almost totally worthless. In fact, he's a negative. Not sure what happened to him, but he can't stay in front of anyone, screened or otherwise. Whiteside looks like a rusty robot with a bad hard drive. His reaction time is pitiful on both ends of the floor. It's almost impossible to run the P&R with him because he can't catch the ball. Add in Joseph being the other half of that P&R, and you have a disaster.
I thought Bagley did a fairly good job of guarding Embid, so maybe Walton will take note and start giving him Whiteside's minutes. That's probably wishful thinking on my part but hey, I can dream can't I?
