Losing the fewest rounds over a 15 fight title streak, having a nearly 90% (being very generous with the term nearly) KO rate in title fights, all while moving up divisions and unifying. If he smashes Donaire like many expect, that’s another world title, another unification and 16-0 (14) in title fights. Just insane. Any other great with 15+ title fights has lost more total rounds in just two of their fights than he has in all of his.
And then he has a chance to become undisputed against Casimero. I've heard that Inoue is "scared" of Casimero. Inoue knocks that kiddy-fiddler out cold in less than 3 rounds.
Lomachenko, Floyd, Manny, RJJ, SRL, Willie Pep You'll laugh at me for including Loma but he is the most mesmerizing boxer ever to watch
