Saengmuangnoi Samson Dutchboy Gym Kratingdaen-Gym Toyota-Thailand 3-K Battery Elite Gym Lukchapormasak was 43-0 with 38 defences of his world crown
Why is he always forgotten when it comes to undefeated champs/titlists, even the Ring has forgotten him on two occaisons, even though they remembered some asian fighter from the early 80's :huh
Don't know why really, but he was pretty forgettable as a fighter. People remember him more for his alleged involvement in the shooting of Warren than his ability in the ring.
Because boxing quite rightly would like to wipe him out of their history, he was not the nicest person to ever step in the ring; ask Frank Warren... allegedly
Marciano died in the plane aksident , he will continue cariere if he will be live. We cant call him retired like champ ?
Jimmy Carruthers retired as undefeated Bantamweight champion but made an unsuccessful comeback seven years later and it was goodbye to his 0,so I don't know if he counts.
A few more, depending on the definition of "champ": Sven Ottke, Ricardo Lopez, Harry Simon (although, evidently, he's come out of retirement), Ji Won Kim
Being an undefeated alphabet champion is a verry small acolade compared to being an undefeated lineal champion.
