I thought Guerrero was going to give Mayweather a fight until I saw him fight Berto. Both guys looked sloppy to me, and Guerrero has to improve a whole lot to stand a chance. I think he would be too strong for Khan, though.
I think Peterson, Matthysse, Maidana, and Josesito might beat him. He would trounce over Bradley at 147. Bradley is way hyped at 147. At 140 he was good, but at 147, the guy just went life and death and lost to Provodnikov. I like how he was hyping some new-found power only to get his ass trounced over. Bradley is like the king of robberies right now.
True but there are some fighter who have retired UNDEFEATED (i.e Marciano, Calzaghe) or with only 1 loss. Guerrero has avenged his only loss, just saying.
He already had a very good career before moving up in weight and gaining some exposure in the last couple of years. Having beaten Aydin and Berto is hardly the focal point of his resume. Still, not unbeatable whatsoever. Besides Floyd there are more than a handful of guys against whom he would be no better than even money.
