Monzon was one of the greatest middleweight champion of all time vs. one of the best super middleweight the undefeated Joe Calzalghe.

Who's gonna win in this fantasy match up??
I don't like the sound of that catchweight. It would benefit Monzon, he'd just have more room to eat, more room to train for the fight, and no worries making weight at all. Calzaghe would have to work really hard to shed those 4 extra pounds than what he is used to shedding. The weight variable really plays a factor in this.
In a weight class where they are both 100% at, Calzaghe takes it.
