Yup, the nice thing about Zollins is if he's on his 3 game upon return, you could conceivably have him play the 4, which would allow KJ to play the (SF) wing player role which he's clearly much better suited for now given his size, and now that his 3pt game has become increasingly lethal and accurate, you aren't losing a spot to a bad shooter.
I might actually reconsider the tank commander unit if you could run out a starting five of Murray, White, KJ, Zollins, and Poeltl. Bench unit would be Tre, Walker, Vassell, McDermott, Young/Landale with Primo able to slide in relatively easily to the 2 or even 3 for either unit. KBD, Young, and dare I say Forbes actually become really nice filler for players having a bad night or for an injury.
*That* team could potentially get hot enough to still find its way into the playoffs, and *maybe* even win a matchup against a Lakers or Clippers or Nuggets or Mavericks.
The only reason I'm even considering getting off the tank crew is that KJ, Walker, and White have really begun to show some versatility (or returned to playing well in White's case) to the extent that when they're *all* playing well, the team is an entirely different beast. Add in the possibilities of what Zollins and Primo could bring you, and decent bench contributors, and you **might** have a team that’s worthy of playing to their full extent.
