Pac and Mayweather couldn't Ko Marquez what makes you think Khan will

[mazdaru]

floyd def carried JMM. he didnt try to KO JMM and what would have been the point? he needed the rounds to knock off any ring rust.

floyd could have ko'ed JMM on the other hand, as you could see, pac wasnt able to ko JMM when he wasnt on PEDs

[FLYBOY]

Khan's speed and punches in bunches will overwhelm Marquez and the fight might be stopped on blood. Khan will win by TKO.

[freeloada]

Father Time will ko marquez.

Co-Sign... he's not the same anymore.. getting up there in age.. losing a couple steps..

[Sweet Jesus]

JMM KOs Khan.

[Zarco]

Floyd could have stopped him
he just never tried to
he clearly carried him for 12

You mean Marquez's resilience, counter-offensiveness, ring IQ, heart, quick recovery time, would never help him to go the full 12 even if Mayweather had been his usual self and brought out that crazy Tazmanian in him with his fully healthy hands of steel?

Cool

Pac fought Marquez at a time where no one was knocking Marquez out, if Pac couldn't do it no one could. Floyd could have knocked Marquez out but apparently decided he would rather pot shot for 12 rounds.

[The Guillotine]

Pacquiao fought Marquez at 130 and was a little drained at that weight. At 140 Manny would murder him.

Mayweather could have knocked Marquez out if he would've just thrown more punches.

IF Khan throws alot of punches it will overwhelm Marquez (look what Juan Diaz did), and he will end up getting ko'ed by an accumulation of flush shots. That is if Khan doesn't go down in the process.

The verdict : MARQUEZ DOESN"T BELONG ANYWHERE ABOVE 135!!!

[Earl-Hickey]

Theoretically, there should be no way he ko's marquez, he is 7lbs smaller than PBF and no-where near as good.

Khan wins, he's too big and quick for Marquez..

It's a money fight for both of them.. A good fight for Khan because he gets to fight;
1) a ring legend
2) somebody who is very fast in his own right
3) a very experienced, very effective counter-puncher
4) marquez still has pop, so if he lands on Khan and he survives perhaps it'll help prove his critics wrong 5) he won't KO marquez, it'll be a UD after 12, after the Salita fight I think it'll be good for Khan to box 12 rounds against a class opponent, at his age it's all about gaining experience
