For me, one of the keys to this fight is that Marco has shown that he has that nasty edge to him when he needs it. Marquez, despite his spirited effort against Pac, can be tentative. Both are highly skilled boxers, but for me Marco is just so smart in the ring and is able to box or brawl. He always proves people wrong...and i have feeling he is going to put together another one of his memorable performances. Should be a fantastic fight.
