I've noticed that several fighters that are very strong don't seem to have a lot of KO's on their records. Tank Abbot for example. He is known as a powerful puncher, but if you look at his record he only has like 2 KO's. Other guys, especially some of these lightweights seem to be able to KO their opponents without being extremely strong.
So my question is does one fighter have KO power and another doesn't? Is in in the technique? Can it be learned at all or is it something you just have to have? I really have no idea and I'd love to hear your thoughts.
