Oden = Roger's Robin -> Robin CoC (?)
![Yearight :yearight: :yearight:](https://i.ibb.co/4W2Xcr6/fat-cat.png)
Rayleigh = Roger's Zoro -> there won't be Two Piece so there's no need for Zoro training the future PK Hippo D. Buffy unlike Rayleigh = there is no need of Coc
Shanks = Roger's ... (here we don't have on Luffy's crew an equal) -> there won't be Two Piece so there's no need of a super apprentice who will inspire Hippo D. Buffy and let him his Top-Hat
Bullet = Roger's ... (here we don't have on Luffy's crew an equal) -> there won't be Two Piece nor Two Piece Stampede so there's no need of a super former crewmate who wants to be the world strongest man and there won't be Meganovas as well as a new MC called Hippo D. Buffy.
Conclusion, the argument of Roger crew consist of 4 Conqueror Haki users makes no sense.
