You keep saying that but you don't seem to acknowledge who threw that power shot or the fact that the particular power shot that was thrown was Maidana's best punch and has KO'd multiple opponents before. Or the fact that Maidana followed that "one shot" up after with a 4 punch combo and Khan still didn't go down. He isn't "chinny"... his "chin" is above average... certainly not Iron but definately above average, I think he proved that in this fight.
yeah, and i loved it when Khan answered with a knockdown, Khans chin = Mayorga's, Margarito's, Pacquiao's chin put together, they would never remain standing taking Maidanas punches.
It's not a thing though. They just call it by a thing's name when it's really a few people wandering around hitting a digital counter they're holding and those are the stats we get.
