No order I suppose 1 John L Sullivan, for putting boxing in the spot lite in the 1880's, and pretty much working on making it a glove sport. 2 Ali 3 Louis 4 Robinson welter weight and middleweight 5 Jack Dempsey for making it a million $ sport 6 Harry Greb 7 Benny Leonard perhaps the greatness fighter of the 1920's. 8 George Dixon for being the first man of color champ 9 Jack Johnson for breaking the color bar in the heavyweight division 10 Jack Dempsey the middleweight for his work in the 1880's I guess? 11 Bob Fitzsimons for being all some. Middleweight, Heavweight and lightheavyweight titles during his run. 12 Henry Armstrong for holding 3 titles at once. 13 Ross, great boxer, 3 weight champ, and carry on the Jewish boxing reins from Benny Leonard 14 Joe Walcott at the turn of the century. Not the heavyweight. 15 Joe Gans, perhaps one of the greatness lightweights ever 16 Jimmy Wilde, underrated, perhaps, but he was the star of the flyweights of the 20's. 17 Jim Corbett perhaps on style. 18 Rocky Marciano's undefeated run perhaps 19 Mickey Walker for his run for the welter weights, up to heavyweights. At one time was ranked 5th in the heavyweights. Unreal for a former welterweight. 20 Ketchel perhaps? No order. Just thinking of 20 guys that transcendent the sport. Its really hard to nail 20 guys as I know I left many off.
