Kalambay by decision. I like Pavlik but Kalambay was a masterful boxer and I think he would be to slick for Kelly.
Kalambay more skilled for sure but Kellys height could pose problems- I think Nunn was the only really tall Middle Kalambay faced and maybe Graham. i think Kelly beats Kalambay because of his natural advantages and he could go to the body really well . i think this is just a wrong stylistic match up for Kalambay.
Kalambay is a style which is bad for Pavlik as many have said. He does not engage and that is what Pavlik always needed.
Style all wrong for Pavlik who was big and strong and best against come forward aggressive fighters who like to trade . Kalambay all the way and wins pts.
Kalambay just too skilled to lose this one, Pavlik can't hit him with that 1 big punch he keeps searching for.
