It's not him, even though he has: O'Dowd Dave ********* http://boxrec.com/en/boxer/31731 (don't know why I can't type this name) Chip x 3 Dillon x 2 Greb Lewis McCoy That's 10 wins against champions for Gibbons - the most so far, so he's now the man to beat.
Most wins. So it will involve someone who surely has multiple wins over a handful of titlists. I bet its on of those old school! LHW guys.
Young Corbett III? It's one of those old guys who fought someone a whole bunch back in the days in the exhibition circuit era.
You're getting very close! We're talking about an oldtimer, who has a total of 16 wins against: 2 welterweight champions 5 middleweight champions 2 light-heavyweight champions
I'm never quite sure who is recognised as world champion or just a claimant but I know Leo Houck beat many world champions and top contenders. He has an incredible record but I don't think he ever got a shot at the title.
