he has a good chance against nate. but i think casa is a bad matchup for pac: great counterpunching ability, excellent and perfectly timed left uppercuts, great footworks, good chin, decent power, and... dirty tactics. i would hope for pac to win but i think casa is the safer bet here.
Katsidis was beating Casamayor around the ring when they fought.. Pacquiao is a much smart fighter than Katsidis and perhaps stronger.. Casa is best at counter-punching, but if Pacquiao was to catch Casa on the ropes, he would go to would pick Casa apart piece by piece.. Casa is past his prime and Pacquiao is a beast at 135..
