Too much defense for Mosley to handle. Many have tried to break that shell, all have failed, and Mosley will too. He is strong but not an ox like many are making him sound like. He has no special attribute to break that shell. He won't and can't. And Mayweather will be sitting in his shell counterpunching all night long as Shane desperately tries to get in. I can't see Shane winning. Especially if Floyd comes out jabbing which I'm sure he will knowing how prone Shane is to it.
