roger loved his sword so much he named his son after it because he's not a swordsman?
keep coping lil bro
as for the davy back fights, why did WB agree? because he thought he could win, you wanna get on your knees and make excuses for wb, but not for harald?
lets also not forget that wb is still a bladesmen, who couldn't make a black blade, just like shanks and roger, and scopper, and ray, and big mom, and shiki, and akainu, etc etc.
Akainu is lucky he didnt run into xebec that day because he would have gotten fodderised, matter of fact i wouldn't be surprised if the admiral he killed is the one akainu was directly under like a steward apprenticeship
Oda specifically made Kaido hype Roger (and by default Shanks, Shamrock etc) for his Haki and not his sword, was because he never was a swordsman. Cope.
And? Rocks didn't get him through strength, nor respect. Its through games, so even fodders like Xebec, Mihawk and Buggy could get him. We know he was just a bum that would've gotten bodied by Whitebeard in a serious fight from Whitebeard's statements anyway.

Harald got near-packed by a bunch of fodders. Extreme diff clashed with Rocks, imply equals. Rocks would've gotten near-packed just the same if you replaced him with Harald as well.
Whitebeard is not a swordsman but a DF fruit user, and even in old age confirmed to fodderise a fodder like Mihawk (WSS):
Black blades are tools for the weak and worthless. Shanks/Roger nonswordsman who are too strong to make worthless black blades. But Green Bull is just about weak enough to make a black blade, so Mihawk with his black blade and EOS Zoro with his black blades=Green Bull.
Xebec is lucky he managed to jump the old era's Green Bull, more like it. Akainu would've melted his shit in. He would've bitched out and ran just like his Sulong Bepo Victim son already did.
Had it been Akainu, and not the old eras Fraud Bull, then a burn pit would've been left where the bum ass crew carried fodder was standing.
