of course he should, boxing is one of the most demanding sports in earth. There should be age limit in boxing and pro boxing needs it much more than amateur boxing.
In Hearns case he shouldn't be allowed fight anyway, he is certainly damaged, look how he speeks etc.
Sugar Ray Leonard knew how to score with Combos (off those flurries and stuff), but Mosley and Roy Jones would landed real effective ones.
those who say that haven't seen much Leonard in action other than Hagler or Duran. Look Leonard vs Green, Price , Lalonde, Ranzany and others. When he planted his feets his combos were devastating.
Floyd Mayweather, Roy Jones, DLH, Sugar Ray Robinson, Sugar Ray Leonard, Marvin Hagler, Chris Eubank, Joe Calzaghe, Felix Trinidad
Trinidad? :rolleyes: He sure couldn't land any combinations against DLH. If someone can throw combos only when other is on the ropes then he isn't good combination puncher.
And Ali wasn't either, fast hands and throwing flurries on bums like Williams or London doesn't make you best combinational puncher. He was throwing arm punches most of the time and only to the head. Not even close to SRR or SRL.
