Jones has a better resume than Calzaghe, reguardless of the outcome imo. Yes Calzaghe beat ATG Hopkins, but lets be honest nobody walked away thinking Joe is the better fighter, he just threw more punches that night and edged him. Yes he beat Lacy, but Lacy is a B+/A- fighter at best. He beat an old Eubank which was still a good win but not career defining. His biggest career win was over Kessler imo because he proved to be the superior fighter agaist another prime legitimate champion.
Jones beat a lot of solid fighters in their primes and aside from Michalczewski he fought the best available at the time including Toney and Hopkins. In his prime he rarely lost a round to top contenders. His wins over Ruiz, Tarver, and Trinidad dont hurt his legacy either reguardless of the circumstances.
