One of the major things people tend to forget is the impact of a great punch. Sonnen rocked Silva with a really powerful punch followed up by some ground and pound that hurt Silva enough to no longer be in control of the fight. Obviously as the GOAT, he always finds a way to win which is why he is the best.(there are better examples out there where someone gets hurt from a huge punch and can`t recover) in 90% of the fights, you get knocked down by a real heavy shot, you kind of lose it for the fight, you are no longer the same and can`t think straight. Now what is the difference between the first and second fight of Cain and JDS? They both got hit early with a hard shot that staggered them BIG TIME... the only difference is that While Cain got knocked out, JDS survived it, but was no longer able to properly fight, he just stuck there on heart and Cain couldn`t finish.. but he paid the price by getting a nasty beating.. if Cain had KOed JDS, we would be talking about a rubber match as 1 ko vs 1 ko I guess what I`m trying to say is that if JDS had landed that exact punch on Cain in the 2nd fight, chances are JDS would have KOed him. So respect to both and the rubber match is gonna be great once JDS KOs his next opponent.
