Vitali Kilitschko hands down. No-one in history could outbox Lewis like he did, and his punch stats show he's easily the greatest heavyweight exponent in history at the sweet science.
obviously pacquiao. yeah jones ir more athletic. yes, mayweather is more well rounded on a technic side. bute what manny did, climbing division after division, leting so many people dream about boxing, because of all his great wars. his career was just another level compared to everybody else in rescent time.
I look at Pacquiao more of an exciting brawler and aggresive fighter than a finest boxer. Floyd and B-Hop for me!
Whilst I respect all on the list, for me Floyd Mayweather is the very best I have seen lace them up. In time the detractors will come to appreciate how good he really was. MF
