Trades are going to have to be made. DA can't play the long game anymore, he has two All-Stars, it doesn't matter how old they are. You try to win every year.
There are no more 'wait and see' seasons. Utah have similar higher end talent but significantly superior supporting cast. Celtics had Jayson and Brown on rookie deals for 4 years and all they have to show is an aging All-Star point guard, a solid undersized center, an All-Defense player who was already on the team, and a bunch of young guys who literally cannot string together two good games.
