Which Was The Most Brutal KO........

[-Kev-]

I felt the Pac-Hatton KO right in my chin, that's how bad it was

I'd go with Pac-Hatton

the hatton one. it came out of nowhere and so early on in the fight. i knew khan would get KO'd.

I'd say Pacquiao/Hatton, just because Hatton was a guy who was known to get in there and throw down. He'd been hurt in the past, and Mayweather stopped him, but I don't think anyone figured he'd get blown out the way that he did, especially as early as he did. Khan on the other hand, while the KO was brutal, I think a lot of people were expecting to be taken out sooner or later.
