Hopkins wasn't near peak for his fight with Jones. The Hopkins of '99 doesn't draw with Mercado no matter what country their fighting in. Jones biggest claim to fame is his domination over a weight drained Toney. The funny thing Jones said Toney was just making excuses and everyone knows it's a big advantage to fight at a lower weight. He used that same excuse 10 years later against Tarver
Many guys carried power, Fitzsimmons Knocked out HW's on a skinny frame no more than 170 or so, same for several others, Hearns at WW he could knock out anyone, Duran an awesome P4P guy and great defense and awesome chin, was easily put out by hearns, that 1fight says it all about his power, He Hurt Hagler in round 1, actually staggers him a bit, but he recovered very fast.
Top 3 for me are probably Sam Langford Bob Fitzsimmons Max Baer Then afterwards I've split ends between McClellan and Jackson. Hearns is probably around 8/9
