Lol bb has always been a character that benefits off others hard work
- steals yami yami from his crewmate that found it
-stealing gura gura and taking over wb's territories and easily reaching the yonko status
Bb is a schemer he takes the easier route not the honourable one like luffy
Lets look at the timeline of some events
-Kuzan and van augur invade wci and kidnap pudding they will def get their hands on big mom's poneglyph as well
- law gets his hands on kaido's poneglyph and is confronted by bb
Its clear that oda is setting up bb to gain 3 poneglyphs (2 from law and one from wci) and a person to read them just like luffy. This would basically put luffy and teach on the same level in the pk race.
law is important yes, but thinking he's more important than blackbeard who has been set up as a major threat to luffy since jaya is delusional
And if oda didnt want bb to get his hands on law's poneglyphs then he just wouldn't have written this conflict in the first place.
Pre yonko bb was already effecting multiple islands with his gura gura + he tanked the shock willie better than big mom did.
Blackbeard also scarred shanks before he got the gura gura, that scar traumatised shanks so much that he went ahead and warned whitebeard. And shanks is someone capable of fighting equally with the world's strongest swordsman.
Law is df reliant, once he loses is df its over for him, he hasn't shown future sight nor does he have advanced amarment or acoc to beat bb without his df. Current bb is definitely stronger than law, though I can see law pushing bb to a high diff in this fight
Bb only appears weak as he's overconfident, in marineford whitebeard says that his cockiness is his biggest weakness
So no bb wont be losing to law, I can see law somehow escaping this but its basically guaranteed that bb will get law's poneglyphs
