I agree with DA. I don't really think the Bulls just saying "wellp, you are both still on the team, work it out" is enough. It is a physical game with lots of intensity, but there is a difference between pushes and punches.
This is a bit stupid, but, when my brothers fought we would go hard but knew to never punch each other in the face. That's a line you don't cross even when defending yourself in these situations.
But that said this issue is one thing but really it's the horrendous guard play I can't take. The bulls strength is definitely their bigs but their entire offense seems to be their guards trying to do pull up 3s early in the shot clock.
