What happened to Juan Diaz?

[nyc champ]

i think for diaz to be a top light weight again he has to beat a good lightweight, such as ortiz, maidana, khan, rematch with marquez

[milmascaras1]

ortiz, maidana, khan are jr. welterweights. only marquez is a lightweight. all of these fighters would beat diaz. he needs to fight a top ten lightweight before fighting for a title in that division first.
