He's 30, he fights at low weights and he has 5 pro fights. His career isn't going anywhere.
Not true. He just doesn't have time to sit and get fed Ws. He would have to pull a Vargas, fighting all names under the sun if he wants to become a star.
will he move up? if so...can he go lightweight?
To me Guillermo looks small I think featherweight or superfeather weight will be good enough someone his size.
