A team that has won a lot of games gets very frustrated on losses and games they should have won. Draymond hates to lose and takes it really hard. If Curry was in the lineup I think Green kicks him the ball? So, the root of the problem is that since Durant came along - Green gets less shots, pt, credit, and I guess that causes some jealousy.
Kerr needs to coach and lay down the law on end game situations. Ok, that might hurt a few feelings. What is the pecking order? Does Klay Thompson give it up to Durant in the exact same situation?
But, Durant should be willing to throw Green a bone once in a while and not show him up. That is Kerr’s job to tell Green privately where the ball goes in that situation. Do it again and somebody else gets end game minutes until he does it the way the coach says.
