With 9:10 remaining in the third quarter, Kristaps Porzingis stepped in between Luka Dončić and Marcus Morris to protect his guy. Nothing special, something you expect to see in a playoff game. But, the refs decided to hit Morris and Porzingis with technicals. As this was KP's second tech, he was automatically ejected from the game. This was Porzingis' first career ejection.
Referee experts said the call was fair, as Porzingis escalated the situation with his interjection into the situation. I vehemently disagree. You won't be surprised that Dallas players and coaches disagree with the call as well. But when Doc Rivers and Marcus Morris both side with Porzingis, you know the call was terrible.
