He gets into it with everyone. Opposing bench players, coaches, even fans. Even in the interview with him, Yoeli, and Haws he got super defensive really quick when Yoeli laughed at something he said. He just comes across as an angry person. I'll miss his playmaking ability, but not his personality.
Honestly it makes me wonder if the coaches chose to only have one hot head on the team which is why they sent Emery packing since Jake is the better player.
