Mayweather. Second best of his era, top 45 all time fighter, but people go overboard talking about him being the best ever. The decade before that people went way overboard on Roy Jones Jr. Same thing. Best or second best of his era, top 45 all time fighter, but not the greatest of all time by a stretch.
