PISTONS: They give up a first they don't need for a younger player who can probably do the same things as Tobias, and become a more significant secondary scorer, which Detroit needs. They attach Tobias's expiring contract for someone who actually fits the timeline.
WARRIORS: They get a win-now player for a disgruntled young talent. They get three-second-round picks as cheap options they can add to a very expensive roster.
KINGS: They get assets for Demar and Ellis, including two firsts.
CLIPPERS: They add some much needed forward depth and shooting + defense with Ellis and Tobias. Two great supporting cast players to a team led by Kawhi and Harden.
