Which is plain stupidity
Which is plain stupidity again, Kaido+BM<Kizaru whom Old Rayleigh could stop and hurt by himself while Kizaru had support of Sentomaru and Pacifistas
he is not faster in all attacks and defenses, just movement speed, old Rayleigh which obviously has to be much slower than snakeman Luffy was able to fight him off, so did Marco
and Kaido was not Tanking deliberately, he couldn't fend off, that is beside the fact that normal luffy was also exchanging blows with Kaido without even going into gears
