can u tell me wt they said coz i dnt remember any sort of such a thing. sorry to trouble u though
its true abt fujitora and other yonko. bt its too early for comparisons IMO. fujitora and greenbull have been promoted recently bt we still do know next to nothing abt their power. heck we still hvnt even seen how greenbull looks like

wt my take on admirals is that we never once saw any of them fight seriously or sometimes they were at huge disadvantage due to locations. example would be
1. MF battle. their utmost priority was to protect MF (and killing ace which is obvious) otherwise MF would be like PH if akainu and aokiji went rampage on pirates
2.fujitora's acting in dressrosa arc. this guy never fought sabo,luffy seriously for obvious reasons.he didnt even participate to help take down doffy bar that push against bird cage. which was the least he could to do since he didnt want navy to gain any praise for taking down doffy. and for comparing rubble feat with bird cage is not quite right when we look at their intentions. bird cage was quite like an end game from doffy while we still dont know a glimpse of wt fujitora's end game would look like. he used rubble to attack pirates who were trying to flee in their ships and helped clean dressrosa at the same time. and he took zero effort in doing so. not only that he fought luffy while still controlling them at the air. i know lot of guys try to bring up how kaido one shotted luffy when they all forgets how luffy in G3 damaged kaido in his dragon form and knocked him out to his human form. all fujitora did was defending against luffy's G3 attacks while not using haki and the only time he went offensive he sent luffy flying away. not only that we all saw how grateful he was towards luffy for saving dressrosa even though he was supposed to capture him. so the guy was never serious on taking luffy on even kill him.
3. the recent fujitora and greenbull vs sabo and revolutionaries. we dnt know wt happened on that battle.and we saw fujitora being injured as well. so its not good to talk abt it right now as we dnt know wt actually happened. bt as far as the details goes we know sabo and rev attacked on mariejois. again for wt we know admirals are at a disadvantage with the location. they cant harm mariejois while fighting. in other words they wouldnt be able to go all out. if u can remember when akainu asked greenbull to send fujitora away fujitora asks shall we go against each other and greenbull reply that he dnt want to bt if anything else he didnt want to destroy the whole place if he could help. implying if went out at each other the place would be destroyed which shouldnt be their job. so in fact even though two admirals were there to fight they at a clear disadvantage while fighting sabo and the co. they probably had to play defense at fight which would explain fujitora's wound plus anyone shouldnt take on sabo lightly as he is now getting hang of his devil fruit.
4. kizaru vs rayleigh. which was the probably the only time admiral could hv went all out if he wanted. bt sadly that admiral was kizaru. the guy is more of a trolling character. he trolling so hard we dnt even know when he would be serious or not. we all know that battle didnt prolonged as kuma sent away strawhats and fighting was over
5. again this is about fujitora. since he is the one, most of the fans use to downgrade admirals bt at the same time we know from fujitora's own words that he was still getting hang of his own fruit. so we may not know for how long bt we know for a fact he is new to DF too. not new as sabo but still new. so considering that we still dnt know much abt his DF strength or his own
and finally abt wt akainu says on how low they are on man power to break two yonko apart. which is very obvious coz garp and some marines(may be other vice admirals as well) are now deployed to return kings and royal families back to their homes. and also marines now hv to deal with shichibukai termination. we already saw lots or troups are deployed on that since now they hv to deal with weevil,mihawk,boa hancock all at the same time. since we never saw any admiral at marineford most probably kizaru is sent for weevil (he knew abt him more than anyone) , fujitora for boa hancock since he is blind and most probably greenbull for mihawk which is not sure bt most likely. with wt we saw only one available was akainu himself at MF and he cant leave that place without anyone to look after it. even then it would take 2 admirals minimum since we got both kaido and big mom and their troops as well. so marines been low on man power was quite the obvious given the situation.
yonko having legendary names is understandable since they roam freely. they fight,rampage and conquer freely without any boundaries to wt they should do or shouldnt . bt at the same time admirals can't do that. they cant attack and fight freely as they want. they are for obvious reasons bound by laws and orders. they cant make a name for themselves if they arent allowed to roam or rampage as they please. even garp who was legendary was only called as the hero of marines. he didnt get any monstrous title for himself like WSM,WSC . same scenario explains how it helped garp being a vice admiral, for taking a name for himself. he kind of had more freedom compared to admirals since they were under the direct order of celestial dragons.
so taking everything to consideration i think its still too early to jump to any conclusions. unless oda proves it with manga clearly if yonko> admirals while going all out
