The World Championships did not exist in Tommy Carlos's Days in running.
Twenty Six, excluding his WCW US title win.
wbo
Thomas hearns (if you include the wbu and ibo cruiserweight belts). Ray Leonard also did it. And so did Floyd Mayweather jr. Also if you include the lesser titles, James Toney did it too but only if you also include his no contest with John Ruiz when he won the heavyweight title and then failed a drugs test.
yes
16 time world champion and a 1 time intercontinetal champion i think
Boxing champions maintain possession of their belts by defending their titles against challengers in scheduled fights. If they win these fights, they retain their championship belts.
you have to win about 20 matches of earn your belts i hope it helped :)
Belts states the level of your expertize in the sport. It also inspires you to work harder to win the next belt!
