It's a good list but I don't think 'Naco' belongs there I've seen him fight before but and exciting fighter is more then just punching power.

I would have my list like this;
ODLH
Arce
PAC
Margarito
PBF
Hatton
JMM
Cotto
Erik
Wladdy

Honor mentions; Chico, JLC, Brewster, Freitas, RMarquez, Valero, PWilliams & Vasquez
