"There could be debate whether Tyson or Ali – or MMA stars such as Rua, Fedor Emelianenko and others – were similarly dominant at the same age. But it would take going back to Sugar Ray Robinson, lauded by most as the greatest boxer who ever lived, to find a fighter who had accomplished more at a similar age than Jones."
"Starting with that match" (Bader), "Jones in his next six bouts faced fighters with a winning percentage of 82.9, who had 78 finishes and a combined record at the time he met them of 118-24-1. All but Bader had held the UFC light heavyweight title. Rua also won the PRIDE Grand Prix and Vitor Belfort won the UFC heavyweight tournament title (though that is not recognized as an official championship by the UFC).
His performance against elite fighters at his early age more than favorably compares with the greatest fighters in either boxing or MMA."
