Fighters who had a loss early but became unbeatable later on

[Flo_Raiden]

Who are some fighters that you can think of that had a loss or two early but became more dominant for the remainder of their careers?
Only fighters that I can think of that remained unbeaten for the rest of their careers after a few loss would be Salvador Sanchez and Carlos Monzon.
Lomachenko could very well be that fighter as well, a dominating force after learning from a loss. People like to sh#t on him for losing to a guy lik Salido in his second pro fight but keep forgetting about other ATGs who also lost very early on.

Badou Jack, Lomachenko

Johnny Nelson had like 10 early losses.

Hopkins lost first pro fight

Juan Manuel Marquez I believe lost his first or one of his first then went on to become one of the best combination punchers in modern history.

Roberto Duran, Manny Pacquaio, Joe Louis, Bernard Hopkins, Juan Manuel Marquez all overcame early losses to become greats.

Lomachenko may in time and so far looks golden.

Rafael Marquez got knocked out couple times early in his career.

[Slyboots]

Nonito Donaire, Adonis Stevenson.

Hagler and Ken Norton were the first that came to mind

JMM is the first guy who came to mind for me.

And yep he got DQ'd in his debut, but would go on to a 44-1-1 (33) record over the next 13 years with only a L to undefeated Freddy Norwood & a draw to Manny in their first meeting as the marks against him. Hell of a streak there even if he wasn't totally unbeatable during that period of time.
