Obviously I'm not gonna persuade anyone here that Draymond isn't the worst person on earth and deserving of every bad call he gets, but if it were anyone but Draymond (or say, a Celtic) I think most here would agree that it was a terrible call. Shoving a guy hard on a loose ball is 99 times out of 100 just called a "foul," or if it's excessive, a flagrant. They cherrypicked "technical" knowing it was the one call that would get Dray run.
But the Draymond half of the call wasn't even the most egregious part of it. After the shove, Donovan Mitchell retaliated by running right at Dray and rage-hacking him hard on a 100% non-basketball play. In no scenario should that be a common foul — it's either a take foul, a technical, or a flagrant. Pretty sure I've never seen obvious retaliation rewarded by the refs in that way. In a strategic sense, you can call it "smart" (and of course "bad for Draymond" always equals "good" or "smart") but it was also the wrong call by the refs. I mean, for anyone but Draymond.
