Who do these belong to?

[Spicoli]

Not all

Papp was undefeated 27/0/2
McAuliffe 33/0/9
Ji Won Kim 16/0/2

Good call. Question always blows me away. Are we talking only world champions? Has to be tons we don't know about. Jemal Hinton was just bizarre!

At the risk of lightning strike...Calzaghe?

[Vendettos]

5-63 Every loss by KO.

I wanna say Virgil Holly (James Holly) as I have my own boxing book and I've seen this, only Holly is 5(3)-55-0 not 5-63-0.

That would make sense fighting to earn money and staying in shape even if it meant a higher loss count. It keeps shelter over your head, food on your table and clothes on your kids.
