2. It is highly unlikely a team will give up a 2014 draft pick. Most of the teams dumb enough to undervalue first-round picks have already traded their picks. The Celtics are unlikely to pick up a first-round pick in a trade unless Rondo, Sullinger, or Olynyk are going out in the deal.
5. Kris Humphries' expiring contract isn't gold. His salary doesn't match up easily with other contracts. I think there is a strong likelihood that he ends up being bought out.
I agree with everything except these two points, which I only partially disagree with.
On point #2: I think there are plenty of teams that would be fine with giving up a 2014 pick, so long as they know its not going to be a lottery pick. You're right that the C's most likely trading partner is a playoff team, in which case it'd probably be a pick in the 20s. Despite this year being a loaded draft class and it being a buyer's market, those late first picks are still always a gamble/project. A team like OKC probably still says no because of their commitment to building through the draft/being cheap, but any of the other top teams (Houston, San Antonio, Indiana, Chicago, Portland etc) would probably rather pick up a guy who can contribute now rather than a late 2014 first.
On point #5: No Humph's contract isn't gold, but silver maybe? At the very least it's bronze. He has good size, can actually contribute off the bench and although it's and awkward amount, it's still expiring. He may not bring back the return that people might expect, but there is some value there and it makes no sense to me that we'd buy him out rather than finding something to bring back at least
some value.
That's Danny's job, to maximize as much value out of our assets as possible, even if it's awkward.
