I think I'll take a chance on the South African Ndou. Pretty Boy Floyd just may try to showboat and wind up on the receiving end of a knock out punch. Ndou will definitely be the strongest fighter Mayweather has faced since Corrales (who he fought a brilliant fight against), but if Floyd doesn't come with his full arsenal, he can lose this fight. I don't necessarily think Ndou will win...it's just the odds are too good to pass up.
