I had some doubts before, and obviously it sucked losing Smart.
But man am I glad we have Porzingis now, and also ecstatic we extended him on a pretty team-friendly deal. He's still just 28 years old, complements the Jays + White well, and his skillset is so useful to have. A 7' 3" big man who can shoot 3s and also make smart decisions. The modern Kevin Garnett
I have love for Timelord, but while he could be a game changer on defense, he was very limited on offense and teams could exploit that particularly the smarter ones like Golden State and Miami. Not sure how they can be as successful against KP though. KP's a big man that can also score from anywhere. Another element for opposing teams to consider. AD the other night had a 40-point double-double but it didn't really matter because Porzingis also had 28/11
He's effective only in a drop scheme, meaning he's vulnerable if forced to defend in space. He's exposed in the PnP, especially against bigs who can put the ball on the floor. We are exposed in the PnR. If we go over, we concede the long 2. If we go under, we concede the 3. We can no longer defend against teams running a 5-out motion offense.
For instance, here's a play from the Lakers game. Porzingis tried to closeout on Hachimura on the perimeter. Hachimura put the ball on the floor and attacked the basket. Porzingis lacks the lateral quicks to stay in front of him and deny penetration.

Porzingis would drop back to protect the rim while Giannis would provide cover on the perimeter with his elite help D. The C's used to run a switch-heavy scheme with Horford-Timelord. That's no longer an option. It's not an ideal situation on D cause Tatum, Brown, White and Jrue are perfectly suited for a switch-heavy scheme.
Offense-wise, he's a terrific fit! Don't get me wrong, I love the trade! Just saying that opposing teams can attack his weaknesses in our defensive system.
