Bass really isn't a prospect at this point. No point in moving Wallace for him.
That trade probably helps the Magic, but it could pave the way for Howard to leave....
Still, you're clearing 18 mil in salaries, gaining a pick and a rotational player in Bass.
You're probably right though, if Wallace is involved in the trade you could probably do better.
Clearing salary doesn't help a rebuilding team nearly as much as young cheap talent.
At the same time, I don't know how much young talent you can get for Wallace. Contending teams are going to want him, but won't have the pieces. And team with the pieces probably don't want him as much b/c he's more of a (incredibly good) complimentary star.
Would the Kings give up on Demarcus Cousins this early?
EDIT: I wonder if the Thunder would consider him
