Damn fine match up. Technically, kalambay was on a different planet. physically though, g-man was a beast. i see gman blitzing him out of the gate. by the third, if he hasnt finished kalambay, mcclellan gasses and kalambay picks him apart for a UD
If G-Man can cut the distance early he'll blast Sumbu out of there. If he doesn't he gets totally schooled as Barkley was.
If McClellan doesn't take out Kalambay within 5 rounds then I could see Kalambay outboxing GMan to a decision. I'm willing to bet that G-Man will find his target though. The guy was an animal and was so good at picking his shots, I don't think Kalambay could last the early onslaught.
