Didn't Aokiji turn into ice to negate the damage though?
This is not a thing. Either you hurt a logia or you don't, and Jozu did hurt Aokiji, but the injury was so minimal that Aokiji only had a lip-bleed and crippled Jozu for life shortly afterward.
Well he did froze his arm that's different from using a brute force attack.
And this is how the Admirals fight. This is how Oda classifies their "strength", it doesn't matter that Aokiji didn't punch Jozu's arm off, what matters is that Aokiji took Jozu's arm off.
You do realize not all yonko crews are structure the same right? Don't get me wrong I still think the admirals win but not all yonko crew members are as weak as the calamities.
The Calamities are like, the strongest Yonko crew members we've seen lol. The only commanders we've seen comparable to King and Queen are Katakuri, Marco and debatably Jozu...so like, the very strongest ones lol. I can't think of any Yonko crewmates we've seen that are stronger than the Calamities, bar
maybe Beckman who is a humongous question mark, and Shiryu who's stock massively dropped when he ate a Devil Fruit primarily useful for stealth rather than actual combat.
So you have two of the strongest Yonko crewmates in existence trying to fight an Admiral with Headliner support, getting completely neg diffed, and then that Admiral directly stating that there is no way an Admiral will be stopped by "a few mere commanders." lol
