I do not know if Guerrero is a "hype-job" or not. I do know that Grady Brewer knocked him out. However, it's always a good idea to review the records. If you go back to the earlier part of Grady's career, and include his early "prospect versus prospect" fights, Grady has beaten 6 undefeated fighters, 5 of them by knock out. That's why I keep saying there ought to be a rule that forbids allowing your undefeated prospect to tangle with the "Bad Boy!" That zero on the other man's record does something to Grady. Something that brings out his best.
He may have to try to go to 147. He doesn't have mustard on his punches. Even last night he hit Brewer with his best shot and it had as good distance as you could dream of and it did not do enough and he could not follow it up. He doesn't have the instincts or the ring IQ. He comes in great shape and has good form but not the mentality of a world class fighter.
