This isn't even close. Marquez did nothing against Floyd except get dropped hard.
A better comparison would be Cotto's fight against Mayweather, which wasn't as close as many choose to remember.
Mayweather was in complete control against Marquez, with quicker reactions to counters. Manny's style meant he was always going to be able to land something on Mayweather. I thought Mayweather shut Marquez out on the scorecards, whereas I gave three rounds to Pacquiao against Mayweather.
Mayweather didn't dominate Pacquaio, It was a competitive fight just that Mayweather was the better man, showing good defense. JMM got destroyed by Mayweather and barely won any rounds while Pacquiao won 4 rounds imo.
JMM is counter puncher
Pac is a volume puncher type of fighter
I would have to say JMM did better base on his style trying to counter punch Floyd .Pac just had to throw without thinking much which he should have landed even more then what he did
