Bradley could come in and start immediately for the Cavs. Give them Pressey also, since he is likely to be cut anyways and Cleveland wants a backup PG.
Cleveland gives up a future first and the draft rights to Russian center Sasha Kaun, Turkish forward Ilkan Karaman, and maybe their 2015 picks, Rakeem Christmas and draft-and-stash candidate Cedi Osman. Those assets get split up between the Celtics and the third team.
Heywood's contract goes to a third team that wants to dump salary. That third team sends stuff to the Celtics. What stuff? Depends on who the third team is. If it's good, the Celtics may throw additional assets into the deal. The purpose of this thread is to get people to come up with ideas of who would make a good third team.
And while the Celtics could take on some of these contracts using cap space, the Celtics may be interested in turning Bradley into a non-guard while preserving cap space to go after free agents.
Maybe Chicago wants to dump Taj Gibson but would prefer the rights to Christmas and the other Marcus Thornton instead of taking on Bradley's contract because they want to minimize luxury tax after signing Jimmy Bradley.
Maybe Denver goes into full blow-it-up mode and gives up Gallinari, in which case the Celtics will probably have to throw in at least one future first.
Houston could offer up Trevor Ariza and either Terrence Jones or D-Mo if they need space to sign a major free agent.
The same goes for the Spurs trying to move Splitter for the same reason.
