The Next Huge Fight?

Joe calzaghe recently stated that IF he wins on nov. 3 he would be looking for another huge fight in the spring. He said he would fight Kelly Pavlik, he would offer alot of money and get a huge fight. If this fight were to happen who would win? The undefeated Brit from whales 44-0 making his 22nd defense of his title, or will it be the young knockout artist with a great chin, heavy hands, who just knocked out the best middleweight in the world. Pavlik already agreed to a fight with taylor at 168 in the contract, but i hear tht no1 in taylors headquarters wants no part of pavlik. If they dont fight who would win Kelly Pavlik(32-0 29 KO's) or Joe Calzaghe(44-0 32 KO's)?
