I'd say Eubank, followed by Reid. The Reid fight was a bit tighter, but the Calzaghe that fought Eubank was greener.
People always say that, and he may well have been but he'd still fought as many pro fights as Haye has now.
Calzaghe says Eubank so who can argue with that? In my view i would pick Kessler due to the fact he was aof a higher calibre fighter (in my eyes). Two great champions.
I havent seen his fight with Reid, but from what I've seen, Kessler gave him his toughest fight even though hopkins got closer to him on the cards. Bika's was more of a frustrating, and off putting fight.
Looking at the answers (not the poll itself) and looking at other fora your oppinion seem to be the consensus oppinion among the knowledgable fans.
