The only fighter in recent history that could have beaten Joe Calzaghe at Middle or Super Middle was Roy Jones in Jones's prime.

Roy Jones before he made Light Heavyweight was the man and always will be the man. No one compares aside form Ray Robinson, who I feel Roy would school if they ever fought in their primes.

To me at Middleweight to Super Middleweight:
1. Roy Jones
2. Ray Robinson
3. Marvin Hagler
4. Carlos Monzon
5. Joe Calzaghe
