because we know, manny is the best fighter in the world, and we know that he will win the fight with floy mayweather...in your own opinion, what is your prediction when mayweather will get knock down of what round/s?..will he become very pitiful, lonely, bleeding nose, head is very bloody and disfigured, or put in the canv until he will wake up in the hospital?
