Whitaker by wide UD

he'd dip, lean away, and block shots all night and counter with crisp combos all night, meanwhile keeping a steady stream of right hand jabs in Pacquiao's face all night

Chavez by UD or 10th round TKO

Chavez would force his way onto the inside and put constant pressure on Pryor on the inside basically nullifying his right hand, if Pyror didn't go crazy trying to trade i think he'd go the distance but lose a decision, if he tried to trade later on in the fight the body shots would have slowed him down a bit and he'd get chin checked and dropped

Mayweather UD or late TKO

basically a replay of Mayweather/Marquez, only Tszyu being less mobile, Floyd landing pot-shots all night to get a landslide UD or Tszyu quitting late in the fight
