If Pacman wins it also means a rematch
It is quite simple, it is 14x odds because of how unlikely it is that it will be a draw. Mayweather has yet to lose or draw and wins by far with points Pacuiao is not going to compete against him when we are talking points as you will see tonight.
The most probable outcome is what the sports are offering in the way of odds. Mayweather win not draw. Of course it means more money but do you think someone with 40+ undefeated fights cares about wins or money?
'undefeated' is what he will be fighting to keep and if he does tonight then he is the greatest that has stepped in a ring imo.
Draw will never happen as this battle is a very tense battle between two best boxer in the world currently. BOth have their own ego to survive and win this match and draw is not likely to happen, either Manny or Pacman wins, so those who bet on draw are only giving away their money.
