I know which current proposed fight (cotto v pac; pbf v jmm) is a bigger mismatch, but who wouldn't be a mismatch v pbf? JMM is a proven talent and p4p top tier fighter who gave pac all he could handle. Do you think people would consider a pbf v pac match a more even bout?
Because PBF is expected to fight at a disadvantage due to him being superior to cotto. Cotto vs pacquiao is ok because cotto is the genuinely bigger fighter but pacquiao has the better skills. With mayweather marquez, PBF is the bigger fighter and has the better skills.
