Ok let me explain the difference between being power, and having a knock out punch... Even Steward said that Hearns didn't have all that much power, but he knew when to use his right hand, and could land it well... He doens't have to hit as hard to be a knockout puncher ...i ts more about placement, timing, and the opponent not seeing it, and he was the master of that, but Winky IMO could take his punch if Leonard could.
