1) Emmanuel Dapidran Pacquiao 2) Naoya Inoue 3) Vasiliy Anatoliyovych Lomachenko 4) Román Alberta González Luna 5) Gennady Gennadyevich Golovkin
As far as being a fan, no rationality: Canelo Benavidez Navarrete Chocolatito Joe Smith Jr These guys have entertaining styles, take on challenges, have come back through adversity, and are reasonably active. Benavidez less than the others but I just like the guy.
Kazuto Ioka, Roman Gonzalez, Nonito Donaire... not any other "favorite" fighters at the moment. Povetkin maybe if he hasn't announced his retirment. Is Chad Dawson still alive?
