Depending how Minn views Bass's contract I see them likely saying yes.
For Boston, not sure who the three younger guys with potential are as Shved will be 25 this year as well as Budinger. Brewer also turns 27 I believe. Williams is the only one with "potential" IMO.
I'm really not a fan of moving Jeff Green right now. His value is pretty "meh" right now so I'm not sure it can get any lower. However, when he starts this year he could put up some very nice numbers which in turn would only increase his value.
All in all, I feel this is selling low on Jeff Green when there really isn't a need to. My opinion on Williams is not very high either.
Derrick Williams is really the focus as far as "potential" goes. The other guys are just younger role players who would fit better in our rotation than Bass / Crawford do now.
I'm not entirely optimistic that Jeff Green's trade value is going to get a heck of a lot higher. He'll have a large role in the offense this year, and he'll probably set career highs in points. But his efficiency might not be really any better than it ever has been, which is to say it'll be about average at best.
In any case, this trade couldn't happen before 12/15 and would probably happen at the trade deadline instead, so Green will have plenty of opportunity to up his value by then. But even in that case, I don't see us getting any substantially better offers than this. The only reason a player like Derrick Williams is potentially available is because he's struggled a bit his first couple of seasons and the position he plays is covered on his current team.
I think if we get the chance to flip Green for a 22 year old with great physical talents and at least some potential to become a really valuable player, it would make sense to take that gamble.
That's the sort of trade we should target with Green. I doubt anybody will ever give us a top 10 lottery pick for him, and we are unlikely to be in a position where we want to flip him for some other productive veteran in his prime (somebody like Gortat or Millsap or something).
