I'm going to put down Duran, since everyone's mentioned all the easy guys. Dude was an old school fighter in the modern era, taking on anyone at an advanced age in a weight class he didn't belong in taking on guys like SRL, Hearns and Hagler. I reckon they're the last set of guys who would and are willing to fight no matter what.
People always knock Roy's resume but they don't get that we love Roy because he was the most frighteningly talented boxer of his era. But Ray Leonard is the most complete boxer of modern times,and excels in areas where Roy doesn't.
no offense but how can you call RJJ the most talented boxer ever there just no way hes a cheat, how do we know in his "prime" he didnt cheat? cheats dont deserve any type of merit or anything for that matter as far as I'm concerned roy jones didnt do **** for boxing. cheaters dont get my respect in no way shape form or fashion. SRL or SRR
