Whisper it, but Marquez could win

After a few quiet months, some exciting fights are on the horizon, the first of which is Mayweather v Marquez this weekend. Mayweather is the clear favourite, but Marquez should not be underestimated. Let's not forget, despite being knocked down three times by Pacquiao in the first round of their initial fight, Marquez went on to dominate the contest and should have been given the decision. Although I didn't see the rematch, many analysts thought Marquez also won that fight. Mayweather has the weight advantage, and is undoubtedly an exceptional fighter. But can he keep taking such long breaks between fights without the 'ring rust' eventually affecting his performance? It should certainly be a great fight.
