His southpaw stance will help against the shoulder roll. I tried the shoulder roll to a southpaw the other day in sparring, my god I didnt know it was so open to the southpaw straight left and hook. Basically, the blind spot which you hide with your shoulder, is not so blind to the southpaw anymore because of the position and angle.
Be aggressive period. He is fast enough to land clean punches on floyd. If he keeps floyd on a defensive mode all night then he has a good chance of winning a decision.
The thing is if Mayweather fights the way he fought against Hatton or Hoya Pac can def win. Just due to his weak offense and inability to throw unless he was truly in danger. Pac wiil pose no threat he will use his feet more than his hands. No matter what people want to believe Pac will dance circles around Floyd. Try and Pick his shots or combos.Then keep it movin. Trading shots with Floyd could actually hurt the smaller Pac who Packs a bigger punch but may be stunned when May actually is ready to engage.You see May hasn't sat down on his punches in a long time but best believe against a smaller man he will play the big man. This is speculation though we can judge a little better after the Marquez affair.
