Buck Smith- he has a record of 179-20-2, 120 KOs.
Just a same list of fighters with over 40 ko's, from different eras.
All these KO's are recorded and have been verified so nothing is anecdotal or heresay or legend.
So I ask you, what have the fighters in your system of H2H done?

He trains my hands for war, my fingers for battle !
