The wheeling and dealing GMs can acquire an envious amount of value, but it comes at a cost. I don't think Barnes would've waived his kicker to make a trade to Utah work, for example. Wright's managed to do very well in trades, but he and the rest of the management/staff deserve a ton of credit for being able to do that while still having a player-friendly culture. Players often don't like being treated like objects, and certain GMs can't see them any other way. Think about how differently the Spurs treat their players, thanking Graham after having him ride the bench for the majority of his time in SA. Kessler very likely feels slighted that he's falling down the rotation so the Jazz can try to pump up the trade value for Collins.
