Now that Vasyl Lomachenko is retired we know that 135lbs. was too big for him. So, where does he rate among the best Featherweights (126 lbs.) to Super Featherweights (130 lbs.) since the 1980's? How would he have done head-to-head with guys like Salvador Sanchez, Alexis Arguello, Eusebio Pedroza, Marco Antonio Barrera, Juan Manuel Marquez, Erik Morales, Azumah Nelson, Naseem Hamed, Junior Jones, Chris John, etc.
Wins some, loses some. Nobody runs the gambit with that group you listed. If I had to bet, I'd say he beats, Chris John, Junior Jones, Nelson, Hamed. Tough to call on the 3 amigo's from Mexico. I'd bet against him on Sanchez and Arguello. No disrespect to Pedroza, I never seen his fights.
