My friend, your choices are full of modern boxers and the 118 pound weight class is full of a century or more of top fighters. You've given us good fighters as options but there are too many greats you left off the list.
Jofre, Olivares ,Harada, and the great Carlos Zarate! This division is so packed I don't think there's a clear answer as to who's the greatest Bantamweight ever and a consensus would be hard to build one way or the other.
Crowcroft, I’ve heard claims that Ruben was actually very overrated and mostly fought forgettable opposition for the entirety of his career, except in the occasions where he lost. What do you respond to this? (I’m not attacking you or Ruben, this is a genuine question cuz i dont know much about him.)
