Surprised there wasn't a thread about it, since its so obvious.
Bum knights are Rev's fight:
Bum knights are after Sabo the most, meaning the leader of bum knights (Shamrock) is seeking Sabo out the most:
There's also an obvious implication of Shamrock being Bonney's daddy and the man who cucked Kuma, so Sabo would also be furious about that and will be avenging him:
This also kinda parallels the brothers:
Dragon vs Garling (fathers)
Sabo vs Shamrock (eldest brothers)
Luffy vs Shanks (youngest brothers) They probably can fight for the one piece at the same time as revs fight holy bums

- Luffy liking Shanks
- Sabo hating Shamrock
