People are forgetting about Gamboa due to his inactivity.

He dominated Ponce De Leon (who beat Broner) and Orlando Salido (who twice KO'd JuanMa).

I wouldn't put Gamboa at #1 due to his lack of a gameplan, focus and tendency to suffer flash knockdowns, but he would be a handful for anyone.

He's arguably the most naturally talented fighter in the world.
