Since TS , Sanji and Zoro didn't have a single legit fight ...
Sanji even more clashed with 2 notable characters in Vergo and Doflamingo and in both cases got used as a hype tool for Law/Luffy fights
Meanwhile Luffy fights all commander level characters and keep progressing slowly and become stronger each time , Zoro at least had Pica and Killer fights but Sanji had none and to top it off imo Sanji/Zoro should'v had a good fight against one of the 6 at the start of the arc and now by the end of the arc they get their second fight vs a calamity maybe even in a tag team
The funniest thing that could happened rn is just if Oda uses Sanji as a hype tool for the 3rd time in a row and let King overpower him for King to end up being a fight for Law/Kidd
