I'm sure a guy who can survive his organs being torn apart twice and keep on fighting isn't getting put down to any modicum of ease.
It was one attack. No top tier is one-shotting any other top tier, so it's not surprising that they blocked his attacks. Hell, Akainu blocked an attack from Whitebeard easily as well, using one leg to counter WB's two-armed, Gura-enhanced swing. Is WB some kind of scrub now?
Jozu was able to stall Kuzan, Akainu's equal, until he got distracted. While I don't see Jozu being any higher than Doffy, his strength is nothing to sneeze at. Especially when he drew blood from an Admiral in one blow, something Marco couldn't do on three separate occasions despite stalemating with an Admiral who replicated Akainu's feat of stopping Whitebeard's two-armed swing with one foot.
