I think Benn vs Kessler would be a great match up.Very hard to score that one.A boxer(Kessler)vs the slugger(Benn).Tight fight to call.Where as Benn vs Calzaghe,now that would go to Calzaghe i think.Calzaghe's chin and great boxing skills as well as his power(when he was in his prime)would have been a little too much for Benn i think.Im being honest here as Nigel Benn inspired me into the sport of boxing as a kid.
