Some perhaps realistic options where in most cases the Celtics should ask for additional assets:
LaMelo Ball (Hornets)
De'Aaron Fox (Spurs)
Jamal Murray (Nuggets)
Darius Garland (Clippers)
Trae Young (Wizards)
I wouldn't trade Jaylen for any of those PGs. None of the guards contribute as much or are as good as Jaylen is.
I would hate to have to watch LaMelo Ball full time. That guy's shot selection would drive me nuts. This team is bad enough already with their shot selection. It would be so much worse with LaMelo.
Donovan Mitchell (Cavaliers)
Devin Booker (Suns)
More complete offensive players than Jaylen. Better ball-handlers & passers. Less capable defensive players than Jaylen.
I don't think it improves us. It changes us but doesn't improve us. I'll keep Jaylen.
Kawhi Leonard (Clippers)
Amen Thompson (Rockets)
Paolo Banchero (Magic)
OG Anunoby (Knicks)
Trey Murphy (Pelicans)
Neither Anunoby or Trey Murphy are in Jaylen's stratosphere. Both struggle mightily to create their own offense. They can only play off of others.
Amen is a long term prospect / project. He could prove more valuable in the long run if he develops his scoring / shooting. But he is definitely far inferior in the short term. Trading Jaylen for Amen would end our title chances in the short term.
Kawhi is too old and too injury prone. Not trading Jaylen for him.
Banchero is an inferior player to Jaylen. He is also a full time PF which means switch Tatum back to SF. I prefer Jaylen at SF alongside Tatum at PF to Tatum at SF and Banchero at PF.
Banchero still hasn't developed his jump-shot or overall scoring enough to lead a team in the playoffs. He had a career high TS% at 56.6% this season which is below average. That drops to 53.3% in the playoffs. Teams in the playoffs do a better job of limiting his driving lanes and force him to take more contested jump-shots. He isn't good enough at contested jump-shots to make that work. He also can't shoot the 3 well enough.
Giannis Antetokounmpo (Bucks)
Zion Williamson (Pelicans)
Evan Mobley (Cavaliers)
Lauri Markkanen (Jazz)
I am not trading Jaylen for Zion. Too injury prone.
I am not trading Jaylen for Markkanen. Markkanen is more limited. More of a one-way player. Can disappear at times. Has never had a high level individual season on a winning team nevermind a title contender. Not worth Jaylen.
Evan Mobley is interesting. First reaction is no but I would think about it. The negative reaction is Mobley has been slow to improve these last few years. He still fails to show up in big games too often. The positive reaction is that Mobley is younger, his defensive game is impressive and his skill-set is one that is hard to find / rare.
Giannis is a good option talent wise. I don't want to do it because I don't like Giannis' game but trade value wise it is a good option. Some risk there with Giannis' recent injuries.
Alperen Seng?n (Rockets)
Jalen Duren (Pistons)
Bam Adebayo (Heat)
Domantas Sabonis (Kings)
No to Duren. He is a basic rim runner center. Not worth Jaylen.
No to Sengun and D Sabonis. I made a longer post on Sengun in one of the Sengun threads. Most of that applies to D Sabonis too. Two similar players.
No to Bam. I don't trust Mazzula / Stevens to use him well. I am not sure Bam is worth JB to begin with but given that I have no confidence in our ability to utilize Bam to his full extent, I definitely have no interest in him.
===============
So Giannis was my only "yes" value wise. Although I hope they do not do it because I don't like watching him play and would rather keep Jaylen.
Mobley was maybe. Likely no.
All the others were definite nos for me.
