Mason would batter Chisora. Easy one to call, this one. Bruno would beat Haye. Froch and Benn is tough to call. Also tough. Khan. Levels.
Chisora outworks Mason Haye is too fast and slick for Bruno Froch to beat Benn. He has the granite chin to weather any storm. Calzaghe wins as that what he does. Undefeated for a reason. Khan beats Taylor with superior hand speed.
In any fantasy match up vs Calzaghe I can never see past a Calzaghe win because that's all he ever did and he had a style that meant he could adapt and do what he had to do, it was quite frankly ridiculous what he was doing in what many consider to be his prime years ie. the Lacy fight and beyond. Gary Mason's record looks very good at first until you see who he was fighting, if you were to throw some of the big or bigger names of his era into that list, other than Lewis, I'm sure the L count would be higher.
