I dont understand how a PRIME Barrera would be a light welterweight? Anyhow: Roy Jones Jr. Vs. Steve Cunningham (Crusierweight) Glen Johnson Vs. Tavoris Cloud ( Light Heavyweight) Antonio Tarver Vs. Chad Dawson ( Light Heavyweight) Joe Calzaghe Vs. Andre Ward ( Super Middleweight ) Bernard Hopkins Vs. Lucian Bute ( Super Middleweight ) Vassiliy Jirov Vs. Danny Green ( Crusierweight ) Sugar Ray Leonard Vs. Sergio Martinez ( Light Middleweight ) Evander Holyfield Vs. Vitali Klitschko ( Heavyweight ) Roberto Duran Vs. Manny Pacquiao ( Welterweight ) God knows. Draw? Thomas Hearns Vs. Floyd Mayweather ( Welterweight ) Wladimir Klitschko Vs. Riddick Bowe ( Heavyweight ) Marco Antonio Barrera Vs. Amir Khan ( Light Welterweight )
Tarver just couldn't keep up. He did box him well, just too slow. Both fights Tarver was around 39-40yrs old. THESE ARE PRIME VS PRIME.
Calzaghe, Leonard, and Hearns shouldn't be compared to many other fighters in their primes. Outside of the absolute legends.
