i think he can to be honest.

jermain taylor has proved recently that he is not a worthy opponent for calzaghe. calzaghe would just outbox his ass all fight.

winky wright is a fight i think calzaghe could win being that he is bigger , stronger and faster and his work rate is good and that could mean he walks away with a decision.

mikkel kessler .. well i can't decide yet. haven't seen any kessler fights to judge him. i will watch some of his fights soon

bernard hopkins .. i think calzaghe would beat the older hopkins because of his workrate. hopkins isn't very active in fights because of his age now. i think if calzaghe boxed with hopkins then big mistake but could beat hopkins if he out worked him which he could do quite easily.

there are more fighters i could name that would be good for calzaghe to face but i can't be bothered typing anymore lol so i will stop there.
