He win, not by KO. KO means that the brain has been jarred against the skull real quick. PAC hitting some with decent, let alone huge traps like Johnnie Jackson, menas that their traps and corresponding neck muscles would prevent the head from snapping back...or that they lack a brain to begin with.
Sorry but this is utter garbage
Do you realise how vulreable a man's chin is?....... Pacquiao may not knock him out with one punch but with 12 rounds and the dude landing 50-100 punches a round you think JOJ would survive?
JOJ is a normal man who has never conditioned himself to take a solid blow, he isnt trained like a boxer and he doesn't sparr. Hes a bodybuilder who lifts heavy weights and he's fucking 5'7. Hes more or less the same height as Pacquiao.
You also have to consider taking a punch when you know its coming and when you are not expecting it.
Huge difference
Boxers are generally KO'd by punches they dont see coming and when their feet are not planted, for example Manny-Cotto when the 2nd knockdown occured it was delivered by a punch during an exchange of which Cotto never saw.
If JOJ atleast tries to fight against Pacquiao the guy will be caught in exchanges and with counterpunches, for 1. he is too slow (handpseed and the ability to get the hell out of the way from punches)
2. the guy probably doesn't have the correct punch form so hes easy to pick apart. No upperbody movement, no headmovement, no real defence to speak of.
People have to realize that mass doesnt equate to punching power entirely, its more to do with form and if you are getting the correct leverage to the punch. This is far more important.
Manny would knock out JOJ is 2 rounds probably, thats if he doesn't decide to absolutely rush him in the first round.
