He absolutely was until last season. I happily admitted I was wrong about him in that he wasn't totally useless on both sides of the court. Now he's just useless on one side. Ideally, LaVine is a perfect 6th man, but we just do not have the talent up front to force him to a bench role. When he stops playing hero ball, he is very good offensively. Still dumb as shit, but he is very solid as a guy who can get off his own shot, can handle the ball and can space the floor.
I'm hoping Markkanen can finally establish himself as the best player on the Bulls (by play and confidence wise) and I'm hoping guys like LaVine can stop thinking he is.
