Mosley is the perfect man for the job of helping DLH, Mayweather will use all of his extraordinary defensive skills against DLH and he will need to as i think the strength of DLH will ultimately give him the decision. I just don't see Floyd landing enough big shots to slow DLH down. Mosley is strong and fast and yes he is a little robotic, however he will give DLH all the preparation he needs for this fight. Mayweather might not get tagged at all by DLH during this fight but will he build up points and win by fighting defensively throughout.
At some point he is going to have to mix it and DLH won't mind that.
