Something has to be done, players can request for a trade if he does not want to play? That's really something. Simmons started it first then we now have Durant and Irving, so now the management are seeing that the players (superstars) are already abusing their right, it's not anymore favorable to the owners who invested a lot of money.
Meanwhile for the other players like Melo, they're even struggling to get a contract and if they do, it's like just a part time for them.
Well, I agree that these superstars that are also drama makers should get what they deserve if they're under a contract and they don't want to play with their current team.
But I think there are punishments already that are deductible to their salary if they refuse to play.
