Might toss in Rafael Marquez in place of Anaya, but it's awfully close between those two. The other fighters listed are pretty much locks.
Not in the same league as the other names mentioned but on his given night Gaby Canizales was a beast in the ring. ...in the history of the BW division in particular there seem to be many guys how could quite literally and seriously punch well above their weight.
Ok, I'll buy that, i just remember Romeo Anaya from the sensational way he ko'ed Enrique Pinder twice back in his title days.
