Maybe, maybe not. The Suns could potentially be out from under Durant and Beal's contracts by that point and possibly reloaded with other (younger/better) talent. Quite possibly, Booker could even be gone by then.
It's by no means a sure thing that it's a better situation, but if Ishbia is willing to spend money, who knows. But yeah, we won't be doing it building through the draft.
We certainly won't be paying either Durant or Beal in another 4-5 years, but bringing in high end talent is going to be pretty much impossible outside of free agency, and that doesn't happen often.
We're going to have to hope that Booker maintains his allure as a star teammate and Ishbia creates an image as a great owner (despite this fiasco).
In the short term:
We can pray Beal gets back, stays back and things improve.
We can fire the coach, and hope this is all because Vogel is incompetent.
We can hope that we find better fitting parts off the scrap heap next summer. This is probably our most realistic path. I think mid-level contracts are going to be harder and harder for role players to get with the new CBA so we there might be some quality players available for cheap. We certainly can't do much worse when it comes to defensive bigs and point guard options.
Or, we can hope someone else is as dumb as we were last Spring, and that supposed offer that could have competed with our ransom is out there, dump Durant for a large return and let him drag someone else into the abyss. But that probably also leads to Booker wanting out, so even it by some miracle a huge deal for Durant presented itself, it would trigger a total tear down while not controlling our own draft.
