I took another look at the 2 punches.
The first punch was a sucker punch, however, it didn't have much power. Ortiz took it and stood with his hands down. He wasn't rocked. It was the 2nd punch that did the damage and was considerably more powerful. The question is, why did Ortiz not protect himself on the 2nd punch? Instead, he stood there, both hands down, both feet still. He made absolutely no attempt to defend himself from the 2nd punch, even though he knew it was coming.
all the guys saying the above clearly do not have any clue.
the first punch hit him straight on the chin, it may look like it had no power but you clearly have no clue what power is or how it is achieved.
force = mass multiplied by acceleration
f = m x a (you should have learnt this in basic physics at school)
this is a simple physics equation
the power comes from the acceleration (speed), not the mass. look at how fast the first punch is and it hits the guy square on the chin. i would like to see your reaction being hit by a speeding shot to the chin (it stuns you or KO's you).
he isn't looking at the ref, he got rattled and ended up facing the ref. the 2nd punch came after less than half a second of the first punch (which was a sucker punch), nobody on the planet can recover that quickly from a punch straight to the chin so basically he was stunned for the 0.3 seconds or whatever it was before the second punch came.
now the most effective way to knock a guy out, is that he doesn't see the punch coming, it's not about the power of the punch but how the fighter has braced themselves for it. for example if you see a punch coming, you brace yourself and it doesn't have much effect, if you dont see it coming, it's unexpected and guess what your either KO'd or stunned.
there was nothing dodgy at all apart from the headbutt (i dont know why he did it, made him look like an idiot, possibly due to his age and mayweather taunting him during the fight) and then ortiz trying to hug and make up in the middle of a round (very idiotic, every fighter is told to leave the handshakes and kissing until the fight is over). the punches were legit and although the first set him up the second KO'd him.
i suggest you guys watch below the full clip

he states "the blow you don't see coming is the one that knocks you out"
that's due to you not being prepared for it. like the sucker punch ortiz was not ready. it also states that the way you throw the punch is > speed but both speed and the way you throw it both count, because effectively without speed there isn't much force but you need force and the unexpected blow. the way you throw it should be straight.
obviously this is a lot to explain to noobies, but i'll let you in on a secret, i boxed for several years and I have had a former world WBC champion come to my home, both punches thrown to Ortiz were legit and the first was enough to shock him and the second was thrown instantly (mayweather took 0.2 seconds to line it up, but it was thrown as soon as it was lined up to hit the guy straight).
first punch (unexpected and fast) = enough to KO usually or severely stun
second punch (straight and fast) = a lot of force and no time to do anything
i have the fight on my pc i have watched the punches frame by frame (both were thrown in less than a second), also Oritz was moving away after the first punch but managed half a step and his arms were already low but they drop, i think this was mainly due to being rocked but with the second punch coming so quick there is not enough time to tell how badly the first hurt him, but the second basically put him to sleep.
i don't believe he had enough time to recover from the first shot and second, there is nothing he could have done, it was over after the first landed. mayweather actually wanted to follow up from the second shot with more, judging by the video but luckily for ortiz the 2nd made him crumble.
