Just saw the first take video for first time.
Matt did not escalate the whole thing. As we know, Blake and Ibaka have a history. Matt remembers last year free shot and non suspension to Ibaka.
Matts' job is to be our enforcer. We have discussed this many time on this board. Yes Blake should step up, but that is why he has teammates. As we saw in last game, A Matt ejection hurts the team less than a Blake ejection.
The whole thing starts with Griffin and Ibaka getting tangled together. They had done this during the game. Blake did not let go and Ibaka took exception. That is how it all got escalated.
