Green is playing OK on the defensive side from what I've seen. He has recently been hitting his jumper. He is clearly being told to stand at the corner and spread the floor on O. I think he is also being told not to hit the offensive glass, but rather to get up the court to be ready defensively. He seems to be thinking too much and his body language reeks of low-confidence. However, he is showing himself in spurts and I still think he may be able to contribute a lot to this team. His salary means nothing to me -- money has been allocated, it's a done deal. His ability to help the C's win is all that matters. He is not a horrible player, but has not shown himself to be a consistent contributor. I believe Doc will gradually push to get him more in the flow offensively -- guys are not looking for him on the wing, they are almost always going the other direction with the ball. Eventually, they will need to push him to see if he can break through, but for now I think Doc wants him to gain comfort and confidence playing D and taking what comes his way offensively.
I am absolutely willing to give it time. Seeing this thread title in the forum topics every day is a little unfair in my opinion. But everyone's entitled to their point of view.
