Yup, and then you can apply that logic to Zoro, etc. If they take in YCs now, what does that say about BBs or Shank's (if fought)? They still may possibly fight the Admirals, another growth level. I really think YCs are a huge jump in strength atm. Also really nothing in the all star fighting styles that point to Jinbe fighting Jack or Sanji fighting Queen at this point. In fact, I see Kid having more of a chance to fight Queen, considering he defeated Snack and probably has the base to take on another YC. Inu/Neko should for all intents and purposes, fight Jack.
The only reason people argue Zoro vs. King (and trust me I did too), was because King has a sword and the idea that he's the number 2, to which we don't even know if Luffy is getting a dedicated fight against Kaido. Hell, I almost expect Who's Who to be Zoro's opponent at this point. Taking a major New World captain under Kaido seems like a better growth point for Zoro, same for Sanji if he faces Sasaki or X Drake or something (idk).
The parallels between Marco and King to be...interesting. We'll see if they actually fight.
