The admirals are not just Sakazuki’s equivalent of kaido’s all stars. They’re actually top tiers comparable to him not just fodder subordinates
In no world are luffy zoro and sanji having high diff+ solo fights against admirals at the same time. Unless Sakazuki becomes insanely strong to the point the admirals are fodder to him surpassing every known character or all of sudden the admirals bec
If Sakazuki happens to be a main arc antagonist for luffy it is significantly more likely that the gap between zoro and sanji’s opponents in comparison to Sakazuki is the same as it was in onigashima and egghead
Aka
Kaido >>>>> king > queen
Kizaru >>>>> lucci > kaku
Sakazuki >>>>> zoro opponent > sanji opp
If luffy can keep fighting characters relative to kaido and kizaru which akainu is zoro can fight characters relative to king and lucci and sanji to queen and kaku
Even against Blackbeard it’s not like zoro is going to fight Kuzan he’s going to have to deal with shiryu. A character even zoro fans don’t like putting above king (despite the fact he is)
By the time zoro and sanji do actually matchup against actual top tiers luffy’s opponents are still going to be significantly stronger
