Apparently the Cavs are willing to trade the Brooklyn pick now, so long as it's for someone that helps them long term. If they made that available in December they could have gotten a decent return but at this point it looks like it will be in the 6-10 range, which is good but not nearly as high or as valuable as it was earlier in the season. I think the best they can hope for with that pick is DeAndre Jordan. Even sending the Clippers the Brooklyn pick they'd have to include Tristan Thompson and his awful contract to make the trade work financially.
I know Jordan can opt out of his deal this summer but I don't think he will, he's due $24 million if he doesn't opt out and I doubt there will be many teams looking to spend that much money on him. Not many teams will have that much cap space anyways and Jordan will be turning 30 this summer, I don't think many teams will be interested in offering him a new contract starting around $20 million a year. The only way he gets paid more than that is if he helped Cleveland beat Golden State in the finals and they reward him with a long term deal but that's unlikely.

The Cav's are supposedly interested in Marc Gasol also but I think the Grizzlies are less likely to take on a contract like Tristan Thompson so getting a deal to work with Cleveland would be hard. Considering Memphis management already fired Fizdale for Gasol, I don't see them letting him go that easily in a trade either.
