Guerrero is a completed professional while Berto is as I've said early on, a rush job who came to let his mistakes grow roots and when he is in deep its basically on the job training. His flaws stand out like neon lights and the blueprint on how to beat him is out. He doesn't adapt and can be easily taken out of his "plan" and his corner almost has seizures asking him to adjust. His handspeed consists of one-two and done followed by a predictable clinch. His power is overstated according to a guy in Guerrero who walked thru his flush, wind up uppercuts. The same Guerrero who was being dumped on his wallet by a one hundred year old Casa not to long ago. Guerrero is the clinical definition of determination between the two as well. I think the last Floyd I saw beats both tomorrow but Guerrero brings more to the table by far, physically, mentally, technically, all around.
