Its hard to just put 3 fav fighters of all time but it would go something like
this
MUHAMMAD ALI, for me ali had it all i think in his prime he would have beaten any heavyweight from any era (yes even tyson for all you tyson fans) the only one that might have given him trouble would have been jack johnson but ali usually finds away to win
even tho i think he was lucky on some of his fights towards the end ie jimmy young fight but the garbage fighter would give anyone trouble,WHAT A SPOILER LOL.

SUGAR RAY LEONARD, for me because i just think he would have beaten alot of fighters before and after him the two fighters today that i think leonard could of beaten and i also think are the two best around today
would be mayweather jr and cotto, i think his great to watch also just a shame he never fought aaron pryor the greatest two fisted fighter of all time and i mean all time.

EVANDER HOLYFIELD, i like holyfield the best at cruiserweight the qawi fight for me is one of the best in boxing history he always comes to fight
i think as a heavyweight he wasnt as good or after 1990 even tho he has one the title 4 times.the bowe fights for me were his best at heavy i also
like the michael dokes fight his second as a heavyweight
