If Mayweather fights Pacquiao the way he fights Cotto, then I see it as a more competitive fight.

If Mayweather fights Pacquiao the way Marquez fought Pacquiao, then he will dominate the match.

But my above assessment can change depending on the Pacquiao-Bradley fight. It will give me an idea as to how much slippage Manny has gone through.

Below 154, Martinez is no match for Mayweather. Above that Floyd is toast.
