The Mayweather vs Pacquiao fight will happen. Its to much money in that fight for it to never happen. Even if it happens 2-3 years from now it will be bigger than any other fight. Pacquiao isnt as relevant as he was back in 2009 but if he beats Rios people will start to think maybe he can reclame former glory. Look what Cottos win over Rodrigez did for him. Now he is relevant again.
