This is all nice.
But we know the admirals took an L here.
We know Fujitora was injured.
And we know they weren't holding back to the extent like previously thought.
As I said before, being injured by Sabo it's not much of an L for anybody in my opinion.
Kaido, the strongest top tier there was, and even a defensive-oriented top tier, got a lifetime scar from rooftop Zoro, who was in my opinion way weaker than Sabo is right now.
Fuji is a top, but he is not stronger than Kaido and most certainly is not as durable as him; he is just a human, not a dragon with impenetrable skin. Hell, WB himself was stabbed and cut by simple swords.
Also, Admirals couldn't go all out. When Fuji got more serious, he destroyed a gigantic part of DR's coastal barrier and moved up all of DR's ruins:
This Is the scale we are talking about.
