We could be good again a lot faster than some people think.
We can be a player in trades for major stars as soon as next year. We have quality guys on reasonable contracts (Green, Sully, Bradley), plus a boatload of first round picks.
We can assemble offers that look as good on paper as the ones that fetched Harden, Howard, Carmelo etc. - particularly if LAC or BKN stumble and those picks are better than expected.
If we get a great player in the draft next year, we can fairly quickly add a third star, perhaps with a couple of picks left over to keep building.
