Green hasn't been a great player for a long time now. I mean he was good by 2016 but since then he hasn't been as good as he used to be, those days when he had little points but a lot of rebounds and assists and played amazing on defence are long gone, he is bad at almost everything
Draymond Green is nothing without his desired teammates, the splash brothers, and the other championship core during their dominance. To cover his lack of good performance, he's now becoming the advisor of their young cores but sometimes, there's might be a time that he is below the belt.
I know Green already realized what he did wrong. He apologized to Poole already. That's the start of forming much-good chemistry between him and Poole.
