that was no where near a "sucker punch"....Ortiz had that coming...actually re watch that fight....Ortiz (who had no business being in the ring with Floyd to begin with) was getting beat so bad, he threw one of the most egregious head butts you'll ever see...the ref called time, took a point from Ortiz, called time in, Ortiz approached him with hands down to "apologize" and Floyd rocked him, albeit before Ortiz was "ready"...completely legal, and more than appropriate.
Floyd has never cheated...hate on the person, the man all you want...most people who hate Floyd, do for that sole purpose, or the excuse that his fighting style bores them...
but until you actually can fathom how much harder it is to dictate your opponents fighting style, and literally have the reaction time, footwork, and counter striking ability Floyd has, stick to watching youtube street fights...
it will always be easier to swing and land a lucky shot, than it is to make your opponents swing and miss...
