Sac need a more than decent vet , plus one or two young players with potential and draft picks.
If det and bos are front runners for the trade
To det: Cousins , Brooks, Salmons
To sac: Prince, Maxiell, Drummond, 1st round pick
To bos: Cousins, Salmons, Thomas
To sac: Pierce, Lee, Bass, Melo
Det adv would be able to offer Drummond and a lottery bound 1st round pick. But then again Sac has stated they want a nice vet to lead them to the right direction. Pierce alone has adv over Prince and Maxiell, especially since these past few years he has helped the celts remain contenders. The celts could still get to keep sully as Sac already has enough pf's on the team and could use a potential center.
So celts lineup after
starters - Cousins, KG, Green/Salmons, Bradley, Rondo
bench - Green/Salmons, Terry, Thomas, Sully, Barbosa
pros: Cousins is young, immature but ultra talented. He has a legit body/post skills of a center and perimeter skills of a sf. Salmons is a decent sf in the mold of Caron Butler and Thomas would finally solve celts issue of lacking a legit 2nd unit pg.
cons: If Cousins doesn't stop acting up even after going through doc and kg. If we struggle on the perimeter and can't close out games bc of losing pierce. (though these days he can't close out many games anyways)
I would really think about making this trade. Cousins though immature also after games , apologizes and realizes his mistakes. He just needs to avoid making them in real time. If sac needs bradley before this trade is considered, i would immediately reject
