Kaido's DF defense is irrelevant vs decent opponents, Greenbull was casually doing damage to same DF without using his best attacks, Kaido's main defense is his Haki when he gets serious, thats why he used Haki to send Scabbards flying in the end:
Or when he gets serious, before Zolo could paper cut him and Luffy dropped him with base punches, then Kaido gets serious defends with Haki and same Luffy punches doesn't work:
Kaido defends with pure red here, you
@Cruxroux clown can see this as well
Shanks or Garp is like that too, Garp was literally called ''Iron'', penetrating their Haki defenses requires special Haki level. DFless Teach had that, Shanks hyped Dfless Teach over Mihawk.
''Teach not having Haki'' claim is as usual Lerrara level stupidity similar to Lizaru being the strongest man and Zolo one-shotting Lucci lmao.
