The fight could have been over after 1 second, as the bell went and Khan had his arm out to touch gloves, Maidana took a wild swing lol. Lucky that Khan was alert and dodged it.
Had there been 1-2 more rounds Khan I think would have been KO'd but credit to him for soaking those shots up and somehow carrying on. He didn't look troubled at all really until the 10th when you saw his legs go, and with about a minute and a half of the round remaining I thought it was definately over for him.
His speed, accuracy and power are right up there but when he doesn't get the early KO and gets hit with shots, it sucks the energy right out of him. He had nothing left in the last 3 rounds, he could barely hold his arms up, he was just in survival mode. Great fight to watch though, if you were falling asleep like me when it started, it woke you right up!
