This is short sighted thinking. Parker, Ginobili, S bag, Butler, Antetokounmpo, Gobert, Jokic, Siakam, etc. were all non lottery picks. Sure, it's unlikely to draft those types at that point, but that's the point: draft picks are essentially lottery tickets and when you're about to enter a re-build, you need as many as possible.
If this team had a reasonably high ceiling, I'd get forgoing that, but anyone who's not delusional realizes they're the an hesis of that.
They can and more than likely will further delay the inevitable by waiting until after the season to purge this roster, but that's risky too because at anyone point, someone could suffer a career altering injury and torpedo their value.
