The ring size will be so important for this fight. A big ring will, as many people have already mentioned, favor Floyd's speed and stamina. In a small ring, with a good/accurate puncher like Oscar, Floyd will eventually get hit (despite his great defense). Having seen Floyd stunned by lesser fighters is what makes me think if he tastes a solid punch from Oscar...he could get into trouble. Oscar is also excellent at finishing off a fighter who he has sparked. But in a big ring, i can see Floyd just using his speed to frustrate Delahoya.
