Nah, I don't think he is worth it. Not efficient enough. Not enough of a playmaker. Be hard to share touches between him, Jaylen, Tatum and Hayward.
I'd rather go out and get a big man. Steven Adams or Nik Vucevic would make a bigger impact here.
Edit: Jrue at his best is someone who needs to play off of others. He is not someone you can build your offense around. If you do, you are no more than a .500 type team and that is with a strong supporting cast. If he is your 3rd best offensive player, you are in a happy place. If he is your #1 (and he would be here because Tatum and Jaylen are not good enough ball-handlers and passers), you are in a bad place.
If DA can get Jrue without giving up Smart/Brown/Tatum I’m all for it. Having Jrue and Smart running the PG/SG role is a defense I’d be happy to watch, only if will fill that Center gap!!!
Now here's a fun pipe dream scenario....
Celtics deal Hayward plus a draft pick for Holiday (Pelicans will want to shed salary, so we would need to send a pick in order to make a salary swap worth it). Celtics renounce remaining free agents and sign Vucevic. Kyrie decides that he wants a max deal with the Lakers, so the Celtics help facilitate a sign and trade. After that, the Celtics use their trade exception in a deal to land Clint Capella (not sure what the rest of the pieces would be).
Next years starting lineup:
Holiday
Brown
Tatum
Capela
Vucevic
There would obviously be some issues with lateral quickness in the front court, which means Brad would need to adjust his switch everything scheme. Capela and Vucevic would be an elite rebounding duo and their offensive games would complement each other very well. Would it work out? Who knows....but it would certainly have strong potential.
On a side note, I'm not ready to give up on Hayward, nor do I believe the Celtics will trade him.
