Agree on longevity - it's just him going from P4P#1 to completely shot fighter happened so fast. And Toney and especially Hopkins ageing much better.
Moore improved as he moved up in weight, it may be the experience he picked up or it may have been that he was a late bloomer...Moores best streak and prime came in the 50+ fights he had before Marciano, he only dropped one disputed nod that he avenged by KO and a DQ loss...most say that was Archie's best
