Common opponent... Kessler Calzaghe beat a prime, undefeated Kessler. Froch went life and death with him... I know styles make fights, but Calz always figured out how to adjust mid fight, a rare talent to have... Froch has shown twice that if it doesnt work, he gets a bit lost... That being said, his drive to challenge himself far surpasses Calzaghes... one good, one great...
