Forgetting the DQ loss in his first pro fight, because i don't really consider that a proper loss but i think Marquez should be undefeated i think he beat Freddie Norwood, Chris John, and Manny Pacquiao. It took a long time for Marquez to finally be a household name for years he was severly underrated plus he was ducked by Naseem Hamed. I really and truly believe Marquez is one of the best textbook fighters of all time if you ever wanted to learn boxing then you can't go wrong watching Marquez, he has great counter punching skills great defense plus he is great all rounder he is willing to fight anyone, he is exciting to watch you got to admire the guy even if your not a fan of Marquez you got to admit he is excellent for the sport of boxing.
