Forget the picks for a moment and put sentimentality aside.
This trade is basically Smart for Porzingis. So what do you get with Kristaps Porzingis?
Well first of all he is a 27 year old, 7'3 center in his prime.
Last season he put up
numbers of 23.2 ppg, 2.7 apg, 1.5 bpg, 8.4rpg, on 38.5% 3 point shooting, 49.8% FG, and 85.1% FT.
So what you are getting here is a legit rim protector with excellent size who can shoot from outside, post up, and when he gets fouled, he can knock down those free throws.
Why did we lose to the Heat, why did we struggle against the 76ers? I think it came down to lack of size.
We struggled to contain players like Joel Embiid and Bam Adebayo. If we had made it to the Finals against the Nuggets we would have struggled against Nikola Jokic.
Porzingis gives us a counter to those talented big men.
Porzingis also adds another dimension to our offense that we didn't have before, a reliable post game. Yes most of our points are still going to come through our stars Tatum and Brown on the perimeter. But now we have the option to throw it in to Porzingis, let him work the post against a smaller opponent and get high percentage baskets in crunch time.
Before the only option felt like make Tatum or Brown create or you're not going to get much out of the possession. Now we have a reliable #3 scoring option.
Now is health a concern, with Porzingis track record yes. But that's been true of our other other big men in Time Lord and Horford as well. With all three of these guys you're more likely to have at least 2 of them available for any particular game.
Bottom line this trade balances the roster from a talent perspective - we had too many guards and not enough big men. Now we have quality bigs, quality wings, and if White and Brogdan continue to play well, we have the guard play to push deep in the playoffs.
I don't even think Brad is done wheeling and dealing yet, but the Porzingis/Smart trade is a significant move that increases our chances at postseason success. And in title town that's what really matters. Basketball analysts like Steven A Smith have already declared that the Celtics are now favorites for the title next season.
FUN FACT: Kristaps Porzingis is 1 of only 3 NBA players to score at least 20ppg with at least 1.5 blocks last season, the other two were Joel Embiid and Anthony Davis. Just to give you an idea of the company that he shares.
