In a few years I think it's possible we can have a lineup that looks like
KO/Zeller
MickeyJerebko
Crowder/Young
Smart/Hunter
Rozier
Maybe IT will still be around. If Rozier is not healthy for whatever reason, Hunter and Smart could start at the backend. Draft/obtain another good upfront player to increase depth
Yeah getting a Ben Simmons would be the icing on the cake. Or one similar future stud. But if not, this would be a solid lineup , solid defense, bbiq, spacing on offense with Rozier, Hunter and Smart all possible to come through in clutch in the 4th.
