Recently someone posted on asking does Andre Wards win over Mikkel Kessler make Joe Calzaghes win over Kessler any less worthwhile. Well no it doesnt.

Heres some examples why

George Foreman destroyed Joe Frazier and Ken Norton. Two boxers who in 6 combined bouts with Ali gave him all he could handle. Yet Ali beat Foreman. Logic would dictacte that Foreman beats Ali.

Tony Tucker beat Buster Douglas, Mike Tyson beat Tony Tucker, Buster Douglas beat Mike Tyson. Surely Tyson Should have beat Douglas.

Thomas Hearns stopped Roberto Duran in two rounds, Iran Barkely stopped Thomas hearns in three rounds. Roberto Duran outpointed Iran Barkely, Who then beat Hearns again.

Finally Ingemar Johannson destroyed Eddie Machen (watch it on youtube it's brutal) Yet Sonny Liston could only subsequently beat Machen on points over 12 rounds and Joe Frazier took 10 rounds to stop him. Doe this make Johannson better or harder punching than Frazier and Liston?
