What do you mean couldn't handle him?..macklin was a tough fighter who could take a punch that night he wouldve given anybody problems even Floyd..What I saw was a champion who adjusted and turned it up a notch and TKO'd him..Again you can't compare the martinez you saw against Macklin vs Floyd..he is bigger, jus as fast, and technically sound enough to give Floyd all he wants..on top of that he has some power..
