There needs to be a distinction between 1 punch ko power and lots of power punches.

P4P,it's easily guys like Rafa Mrquez,Edwin Valero,Ponce De Leon,these guys can turn fights in a second Guys like Pavlik hit tremendously hard but not with 1 punch,it's more than 1 punch but he is a monster! Pacquaio obviously and I think Cotto deserves a mention too.
