I can top that easily Charles Goldman had over somewhere between 300 and 400 fights in his entire career but since it was waaaaaay back in the day most of his matches went unrecorded throughout boxing history, if you went to boxrec that record is incorrect since about 300 of his fights went unrecorded BUT he easily beats Reggie Strickland
And it’s not known basically because history starts Wilde’s career in 1911 but he had been fighting as a professional for about 3 or 4 years before that He probably didn’t have 800 bouts, but I would say it was probably closer to 5 or 600
Billy Bird had 330 recorded bouts if thats what you’re looking for, in “recorded” bouts he’d be second behing Reggie.. but in total professional fights(recorded and unrecorded) Billy Wilde. Of course because the first 4 years of his career are unrecorded lol
The old fighters like Moore were battle hardened. I know people talk about the dietry & physical advantages that todays fighters have but I’m not sure that compensates for the experience & toughness of these old pros. Also boxing was so much more popular in those days in terms of interest & in the numbers of fighters as pros, the competition must have been fierce. These things seem to be overlooked when comparing old & new fighters. I’d pick Louis, for example, over Holyfield any day, I’d fancy him against Tyson as well.
