I'm late on this but in case you missed it do yourself a favor and check out Brin-Jonathan Butler's portrait of Manny Pacquiao for SB Nation Longform:
After eight frustrating years, four controversial fights, 42 contentiously scored rounds, with over 500 punches landed from more than 1,800 thrown, after two grueling hours of opportunity under the spotlight, on Dec. 8, 2012, Juan Manuel Marquez finally landed the punch of a lifetime against Manny Pacquiao. It happened with just one second left in the sixth round of their mythic saga. Pacquiao charged forward to land one final blow before the bell, and instead added his own momentum to Marquez's immaculately-timed, coup de grace right-hand, which landed flush against Pacquiao's jaw. On TV, when the punch landed, Pacquiao's back was to the camera. The reverberations of the impact were only detectable through the sudden jolt of Pacquiao's wet hair on the back of his head.
But isn't this a staple of wrestling, meant to fool? Since the punch itself had landed with such comic book emphasis, the traction of the unfolding human drama, along with reality, became unhinged and, for an instant, suspended. In confusion and disbelief, many people watching around me in a New York bar laughed in horror. As Charlie Chaplin famously pointed out, from a distance, a man slipping on a banana peel or stumbling down a manhole is funny. It's something altogether different up close. And since Pacquiao had fallen face-first and remained motionless, almost fastened to the canvas, there were no cues.
