George Foreman’s comeback and winning it at age 45 is up there (but I agree on Armstrong). (Also the George Foreman grill.)
Well, Ceferina Garcia wasn't the Middleweight Champion ... so, the Triple Crown is fine. John Ruiz was recognized by more of the world as heavyweight champion when Roy Jones beat him than Garcia was as a middleweight champ.
Well yes, sort of, by the time he fought Garcia in 1940 he had already given up the FW belt and lost the LW title back to Ambers, so he would have not have had 4 titles at the same time, also the MW " title fight was only recognised in California , that aside, agree he was prob the winner, plus he had already beaten Garcia in a WW title defense ! stay safe buddy.
As mentioned, I too would pick Armstrong's triple crown. To think during that period he went 46-0 in 32 months.
I like some of the answers I’ve already read here. Foreman’s winning the crown at forty five and after having two careers divided by a decade of retirement. Henry Armstrong simultaneously holding three titles at once. I would also like to ad Chavez reaching 87-0 or whatever it was. And Bernard Hopkins being a champion at the near age of fifty
Louis keeping hold of THE Heavyweight Championship of the World for nearly 12 years also deserves a mention.
