Couple of good names, most were jsut not good enough to take the title when they had the chance though, so my vote has to go to Peerless Jim Driscoll.

Before Jim went to the states, all the boxing scribes, fighters and promoters knew of him, his repertation hit the states long before Jim went there. Finally when Jim hit the states he was beating everything the Americans had to offer untill he got a chance at the world featherweight title against the champion Abe Atell. It was unfortunate for Jim that he fought in a time where the champion could dictate the type of match they fought, and at those times they done a lot of No contest matches, they were basicaly if a fighter could not knock out the champion in 10 rounds the fight would be ruled as an NC, and Abe Atell would only fight Driscoll under those terms.

At the end of the NC fights the reporters would give their scores on who would of won the fight on the score cards for betting purposes, Driscoll won out right on the cards, btu sadly it went down as a NC a she was unable to knock Atell out, and Atell kept the belt. Although mot of the boxing world all considered Jim the champion, he wasn't officially.

Not long after that Jim spent 6 years in the army through WWI and by the time he came out the champions were 10-12 years younger than him, he was past his best but give it a shot.
