My top three heavyweights of all time are:
1) GENE TUNNEY, 82-1-3. He was 3-1-1 against the only man that ever beat him, Harry Greb.
2) ROCKY MARCIANO, 49-0, with 43 KO's.
3) VITALI KLITSCHKO, 35-2. Vitali has never been knocked down, and has the highest KO percentage of all heavyweights (34 of his 35 wins were by knockout). Vitali was ahead on the judges cards at the end of all of his 37 fights.
But the best may be yet to come - there's a lot of young, talented boxers in the heavyweight division, such as:
ALEXANDER POVETKIN, 11-0, who won the Gold Medal for Russia (Super Heavyweight class) in the 2004 Summer Olympics,
DENIS BOYTSOV, 17-0, turned 22 in February, and
ALEXANDER DIMITRENKO, 24-0, 24 years old.
