I just read Guerrero has won 4 out of 4 in championships. I thought he lost to a veteran fighter at 126 in the past? I feel he is going to be a much stronger and better fighter at 130.
He was beaten by an overlooked gamaliel diaz and avenged the loss in impressive fashion. He was also schooled by orlando salido, but the verdict was reversed after salido tested positive for performance enhancers.
he was also beaten by Orlando Salido and then Salido got called on a bull**** steroids charge according to many reports. Guerrero is barely world class imo. off the top of my head I would favor Juarez, Barrios, John, Linares, Valero, Gamboa, Soto, Antillon, and Luevano to beat him
