Could Pacquaio have knocked out Margarito?

Nah.
But I'd rather get knocked out cold than what happened to Tony.
(Margo has too much heart, Mosley didn't KO him & he unloaded)

Ref stoppage... Yeah maybe.
(It should have stopped)

 

I think Cheato was ready to go but Pacquiao decided he'd cruise the last couple of rounds no doubt he was aware how much damage he'd done so to answer your question YES I think he could have finished him but chose to let it go 12.

 

Not whenever he wanted, but in rounds 10-12 if he had the old killer instinct he would have gotten Margarito out of there. He just cruised when he saw the egregious damage he had done already and knew that Margarito was no longer a threat.

 

Literally knocked him out? No.

Kept up the pace and forced a stoppage (that might not have come)? Yes.

He was looking at the ref a couple of times like 'aren't you going to stop this?'

If it were any other occasion, the damage to margarito's face could have had the fight waved off.

However, Margo was still coming forward, throwing and landing punches until the end of the fight..

 

No but could have made him pass out from brain damage


Pacquiao was going easy on him towards the end rounds and having fun

 

He definitely wasn't trying to stop him the last round. He just threw pitty pat punches because he knew he had it won and probably didn't want to cause him any further brain damage. If he had teed off on him in that last round he definitely would have stopped him.

 

If he put his foot on the gas I believe the ref would would have stepped in. Still though Margo's corner should have pulled him out.

 

if pac did not carry him in the last few rounds, he could have stopped him via referee stoppage or his corner could have thrown the towel. but if pac has the same fire as he has in the hatton and the cotto fight, who knows?

 

Of course he could.

If he gone all out.

Only an idiot would disagree.
