To me it isn't even a question. Mayweather by healthy decision. Pacquiao will have his moments but by the 9th or 10th round, Mayweather will have a good lead in the cards & it'll just be Mayweather pot shotting a chasing Pacquiao.

Pacquiao wins by beating people up. I don't think he'll be able to beat up Mayweather in the way he needs to. Mayweather outboxes his opponents & we've seen Pacquiao outboxed by lesser boxers before.
