Mayweather's corner is a nonfactor, just a facade. Uncle Roger might be at his side, and Floyd Sr. likely will be screaming instructions from ringside on Saturday, but young Floyd does as he pleases when he pleases -- and he's almost always right, by the way. Guerrero has an advantage in this department. His father and trainer, Ruben, offers a keen perspective from outside the ropes and delivers instructions between rounds, and Robert responds by executing them. Guerrero is disciplined and attentive in dealing with his corner. Although Mayweather often knows best, the same can't be said for him.
