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.
Hopefully, their old way of interventing to each other is back. But I guess there's already a stain and it's not that quick to be gone. Well, as for Draymond's status.
Stephen Smith said that Green wants to play for the Lakers. This news is out just a few hours ago.

After the incident, I also heard a lot of rumors about Draymond Green getting shipped. Early this morning I was scrolling through some news and I saw a post with Jimmy Butler mentioning that Miami Heat's defense will be different if Green joins them. And there is also Green wearing a Dallas Mavericks jersey. Maybe some teams are now starting to offer the Warriors for Green.
