If the Celtics wanted him, they could have offered him more the the vet min to get him once he was waived.
Possibly. Maybe he'd have preferred to sign with the Clippers. They're pretty good. And the dude's already made a fortune.
If you trade for him, he's yours -- and you get assets instead of giving them.
The fact that you have to be paid to take that contract, do the Celtics really want that contract? It's not like they could then turn around and use it to get another piece.
It's impossible to use an expiring contract to get another piece? Most of the speculation about the resulting TPE has been about guys making $20-28MM..... not a huge difference between that and Batum's expiring if that's how it's used. And I believe Batum would have had his Bird Rights after this season, as well.
Regardless, if Wyc's OK with the money, i'd rather pay Batum for a season than give Thompson $19MM for two.
Re: the luxury tax, I believe it would be been very close had they taken Batum back -- or they'd not have offered Hayward $26.5MM per over 4 years. And remember,
Hayward opted out of $34.2MM for this season to begin with. If in fact they'd have been slightly over (even without Thompson) -- fine. Danny's an excellent transactional GM. Dump Edwards or Green, or the like, to get under.
