What the heck are you talking about?
You do know your geography
Without arguing over your highly debatable first statement, my biggest issue with the Smart Porzingis trade is with what both players bring to the team.
Porzingis is mediocre on defense and on offense only adds one more player to the "give a scorer the ball and stand outside the 3point line" offense that the Celtics have been unsuccessfully running for years, and on top of they already have Tatum and Brown that are both better than Porzingis in ISOs, so all that he adds is a 3° option to a system that wasn't working with two great ones.
On the other hand no one will argue that Smart is not a good defender and you may say his decision making isn't that good on offense, and I agree with that, but in this last playoffs he was the Cs best playmaker, mostly due to the fact that most of the time he was the only one.
So with that trade they have basically worsened their defense in favor of having a even more static offense which already wasn't working for them.
Holy... It takes two and Undertale, what a great update.
Man, mad respect for engaging and calmly responding to a guy like that.
