Tbh when ppl say BB will surpass all other Yonko because he will be end game opponent for Luffy
My take is the same but with different perspective
BB no matter how strong he will get, maybe 3 DF or some shit.
He will always take some L that force him to play dirty
He was always portrayed to be the real life scummy coward and smart pirates
When he was always talking highly and looking confident Oda always give him some L
Confronted Magellan like he was a boss but got one shotted instead.
Only fighting WB while he was at death doorstep and still got crush prompting to gang on him.
Needed help from Coby to beat Whangzi.
Pull back from Old Ray etc.
He'll act confident and underestimate Law again, that would make him to play dirty again?? Let's see if Oda is consistent with his BB writings
