The winner take all thing or the winner takes the bigger percentage thing is stupid. In a world where we have so many bad decisions you are asking these guys to let the judges decided their pay? Another thing is that you are setting the sport up for more corruption. I could just imagine how many people will be on both sides payroll to make sure that eveybody, and everything in the arena is in their favor. From security guards to waitresses they will all be offered a piece if their fighter wins. The elevator host may put anthrax in your luggage. This would be like Goodfellas 2012. Real dumb idea.
That would favor some fighters. There would be nothing to gain for Mayweather it´s highly unlikely that he could Ko Manny
