The way I see it is this: Top Rank's top fighters in the 140-147lb divisions are Mike Alvarado, Bandon Rios, Manny Pacquiao, Juan Manuel Marquez, and Timothy Bradley. I believe that the decision for Marquez will be due to his drive to either catapult his legacy by becoming the only Mexican fighter to become a five divisional champion or to earn the most money he will ever make in his career, retire, and live prosperous for the rest of his life. Marquez is really in the driver's seat no matter which way you look at it. Say that he doesn't fight Pacquiao or Bradley later this year, he can fight Brandon Rios or Mike Alvarado and make great money, especially if he fights in Mexico on Mexican Indpendence Day. He can still go for Pacquiao or Bradley in 2014....
Do I think he can beat Bradley? Yeah. If Bradley gets hurt like he did against Provo, Juan will stop him. Bradley better come in shape and ready to use his speed and not stand right in front of Marquez.
