I saw the video of the Embiid kick. Claxton did kind of step over him and taunt some, but Embiid's kick was entirely unnecessary. Based on the other recent action with Green and Harden, I don't see how they can't suspend him one game. Luckily, PHI is up 3-0 so they can suspend him with minimal impact.
And I can't believe that Harden got ejected for that. He pushes off with his arm like that every time he has the ball. It just happened that it lined up the wrong way in that case. Usually that push off would end up in the chest. It is barely a foul. I also thought Claxton's second T was pretty soft (actually saw that part of the game).
