Enzo Mac although he didnt become champ by actually winning a belt but rather had it handed to him by the corrupt FWRRn.
He earned that belt. even though he lost it real fast he earned it fair and square. Im not gonna diss the man and say he wasnt meant to be a champion. He was ment to be a champion. just for a REAAAAL short amount of time.
Micky Ward? He was the late stand in sort of fighter for years before he won a title. Not really a journeyman skill wise but maybe on his record.
