Prime Kostya knocks out Manny in the final minute of round two.

No, but in all seriousness, I think he was too good for Manny and would hurt him BAD. If he was getting rocked at 130, Kostya would be making his legs twitch involuntarily and on a regular basis. He wouldn't last. And that's no slur on Manny, it's just that Kostya was that good at his best. Kostya was a good technical fighter and wouldn't hand Manny his chin on a dish.
