i say most definitly one of the greatest hw's - mayb not the greatest--but certinitaly up there. his claim to faim: never lost a fight. i guess there had 2b atleast 1 hw with a perfect record. so alltime great or not?

i think hes 1 of the greatest cuz his best attribute:heart

he was undefeated cuz of heart--doing whatever it takes 2 win the fight, not giving up. he reperesents the true spirit of boxing--

he was a cool fighter 2 watch because his punches looked like he was throwing fast balls -throwng haymaker after haymaker

his stamina was unbelievable-like the energizer bunny--just keeps going and going
y people dont like him--his opposition--which wasnt all that great but it was what it was. if u look at it joe louis had the same quality opposition. marciano never lost a fight--never took a fight lightly--and no1 can ever take that away from him.
the main reason i put this guy in my top 5--is because of heart.
