Given by the fact that Kaido's supposedly equal lost to two YC1 i highly doubt that Kaido could ever solo two Admirals but sure maybe he can hold his own.
I never undertood those comparisons, every YC/Yonko/Admiral is different from the other it’s not maths it’s not 1+1=2 there is more to it, Law and Kidd fruits are very versatile And strong fruits (even before awakening) and even with that they seem to have took more damage than BM even if she’s « lost », BM lost due to the environment and even when she was falling she told them not to think she can be killed like that.
We saw a dying WB beat the shit out of Akainu so yeah a Yonkou can hold/beat two admirals, the yonko’s are the strongest beings in OP we are in chapter 1046 and poeple are still arguing about this ?
