Toronto moves an expiring contract for a shot at a younger guy (on a short contract) possibly fitting in there.

Denver gets a more consistent backup big man for the playoffs (Jordan shouldn't play in the playoffs, Zeke and Saric just don't fit there).

Portland takes a flier on a young big (Zeke) possibly getting better with more consistent playing time. Saric is just salary filler and Portland gets rewarded with a future 1st for taking the bad salary in this scenario.
