Good call on Galaxy, might be the hardest punching southpaw ever. Maybe not an all time great Zaragoza was a really good Mexican southpaw. Naseem Hamed hasn't been mentioned? I didn't like him but he's probably in the top 10. Obviously Whitaker, Hagler and Pacquiao are the 3 best though imo with Whitaker as the best. Winky was a personal favorite of mine too.
