For this year they've got no choice but to try to prepare for the playoffs as best they can, but if it's an early exit, they have to face the uncomfortable reality that trading Giannis and whatever else you still can and getting younger might be in the cards. I'm guessing they'd probably prefer to try running it back more year, but I can't justify in my mind how they're going to get any better. They've hitched their wagon to this core and they don't have the assets to really do much more that's going to move the needle. And if Giannis isn't happy, he might force their hand anyway.
It's unfortunate, because you always felt like this group was capable of more over the last 5-6 season. Fortunately, they do at least have 2021 to hang their hat on and always will.
There's still enough really high end trade value in the stars of this team to accumulate good young value and try to be back to contending sooner rather than later. Unfortunately in the NBA, unless you find "the guy", there are no certainties going forward.
