People are always going to undermine a champions accomplishments. Usually it changes once they've retired and been looked back in history. Has happened to Leonard, Jones, Mayweather and now Pacquiao.
The man's talent and drive let alone gives him a "chance" against any of the greats. Not saying he'd win but it's stupid to ever count him out. I don't know how any fighter can go 12 rounds without being hit flush at all when fighting Pacquiao. The footwork, angles and hand speed isn't comparable to anyone's right now. Freak of nature!
I don't see Margarito's power being much more threatening than Khan or Ortiz's. Ortiz the harder puncher but Khan throws in greater flurries accumulating the same effect. Maidana is tough as stone. I don't see many people stopping him unless it's Pacquiao. That deadly overhand right of Maidana's could really slow him down. Not only that in clinches Margarito is horrible. Those would be times Marcos could really rough him up. It's be a dirty and exciting fight
Well... granted Khan isn't as smart as the typical Indian you'd find at your local University or what not but clearly there is no "definite" answer for hurt. There is a lot of ambiguity when talking about being hurt.
If having your eyes glossed over in no-mans land running around like a wounded jack rabbit in complete defense mode isn't hurt than so be it. He obviously doesn't qualify that as hurt. He about did the Zab Judah but with more flair to it cuz he kept going with it. He seriously looked as if he'd gone 8 pints deep and was stumblin to the beat of a Irish river dance. He's like the kid that got too drunk at prom and could barely stay on his feet
