This is a tough fight to pick. But for me, one of the key factors is the fact that Marco has shown that nasty edge when he has needed it. He will try and win a fight anyway he can...box, brawl, or both. Marquez showed a lot of spirit against Pac, but he can also be tentative. In his recent fights he has tried to come out and be a big puncher to look for the knockout...to please fans and get attention for a big fight, but i just don't think his style is suited for going to war. Whereas Barrera can switch from boxer to brawler as well as anyone. It will be interesting to see what tactics each fighter starts off with. They are both great Mexican fighters...so you know neither will back up or back down. I'm picking Barrera by UD, because i have learned to never underestimate him. Should be a fantastic fight.
