I'm gonna go one small step forward and say EVERYBODY WHO EVER BOXED! Seriously, though, it's gotta be a welter weight. It'd be great to see Ali or Tyson vs. Wvlad or Hagler vs. Pavlik, but bring back Hearns or Lenord. Hold on lemme get a coin to flip....got it. Heads for Hearns, Tails for Lenord. Heads! Hearns. PS Make this a poll, duh.
Roberto Duran in his prime around 1978-1980, I think he beats Pac at 135, Hatten at 140, Cotto, Mosely, Williams, Margarito, Cintron and Floyd at 147 and De La Hoya at 154. Or Hagler in his prime around 1980-1984. Would be interesting to see him against Pavlick, Taylor, Trinidad, Calzaghe at 168, Jones and Hopkins at 170.
