On a seriously tip though, Mayweather could out fight Pacquiao simply because his right hand is better than Pacquiaos left in the sense that he has better timing, a considerable reach advantage and has enough power to upset Pacquiao... It's no where near as dynamic but then it doesn't need to be because Floyd has a near complete arsenal.

To be honest, it could be even simpler than that... Mayweather isn't a one hand fighter in disguise like Cotto or Dela Hoya and is stronger, quicker and has better timing than Juan Manuel Marquez, Barrera & Morales so he really could have this fight in the bag with his 1,2&3 head and body.
