Yh but that’s because Roger ended Rock’s era?
Moreover defeating Rocks was Roger’s biggest battle accomplishment so you can’t really separate the two. In addition, Kaido lived the Rocks era so isn’t it weird that he’s using Roger as the gold standard for strength & the path to pursue if Rocks was indeed stronger?
What does Rocks being above Primebeard have to do with Roger though. Again not to undercut WB’s feat against Roger but it was a bloody friendly/exhibition match lol where as Roger v Rocks was a death match. The two are not the same. Moreover Roger was already in decline due to illness during that fight.
Kaido used Roger because he’s the only one to become the pirate king, but it’s clear that Rox didn’t have that ambition and instead wanted Imus throne. And Rox’ era was ended by a combination of Roger Pirates, Marines, and WG fighters. It was not ended by Roger and his pirates themselves.
Whitebeard by every metric was at the very worst ~ Roger. Roger even if you have him stronger, is still approximately equal to Primebeard. As such Rox being named stronger than Primebeard sounds like odas way of saying he’s stronger than Roger as well. I mean, why else would Oda have Roger be rivaled with two of Rox’ subordinates
