I've said it before and I will say it again- Sanji fanboys dreams do not coincide with either Zoro's, nor Sanji's.
They will not be tag teaming against anyone.
This is especially true if said opponent is a swordsman.
I would rather have Zoro be capped at Who's Who level solo, and not partake in fighting against kaido, then him teaming up against a calamity especially if it turns out to be King. I don't give a rat's ass who you think he's gonna tag team King with, be it the scabbards or Sanji, it's still a garbage idea nonetheless.
