I feel like he has outplayed Brandon Bass.
And yet the coaching staff doesn't. Why?
My guess here is they see Bass staying late at practices. They see Bass giving 100% effort in every game and every practice. They see Bass hitting the weight room regularly and sticking to a proper diet. They see Bass acting like a pro.
So perhaps what they are doing is saying to Olynyk, ""want to play, be like this guy, act like this guy, emulate what he does and how he acts". I am not saying KO is a problem. Not at all. Its just young players don't usually have the work ethic, dedication, and attitude to do what you have to do to be ultra successful.
Olynyk is getting minutes and he plays a position the Celtics are loaded at, PF. He is a rookie. Make him pay his dues and let him change to be more like a professional like Humphries and Bass. When he plays well, play him more minutes. When he doesn't sit his but. He's a rookie. Part of the growing process is learning that you are never given anything. You have to work to take it. Since Olynyk hasn't taken that spot my guess is he isn't doing the kind of things behind the scenes that the coach and management want him too.
Notice Sully has been demoted as well. Clearly, at least IMO, a message is being sent to the young guys.
