Do you think Manny Pacquiao is the greatest fighter of all time?
Alex Mortel: There are too many different eras and weight classes to account for to declare anyone the greatest of all time. Pacquiao is the best right now.
james (@keon2214): Pacquiao is barely the best boxer of the decade. His level of competition has been very poor, so he's had few quality fights. He's just the best of a bad lot.
Sam Pfeiffer (@ sampfeiffer): As soon as Pacquiao gets in the ring and beats the undefeated Floyd Mayweather Jr., he can be labeled the greatest of all time. Until then, no.
Mark Giongco (@ mg_onpoint): No doubt! He has the speed, power and heart of a champion. I can't think of anyone else who had the complete package.
Mike Minoff: He's probably in the top 20. I'd rank him with Marvin Hagler, Evander Holyfield and Mike Tyson, but he's not in the same category as Muhammad Ali, Sugar Ray Robinson and Rocky Marciano.
