I see no upside, no good ending for Mayweather if he agrees to this fight. If he kills her with one punch, he will be hounded by people for the rest of his life. Some will probably even want him behind bars. If he loses to her, he’ll be the laughing stock of boxing.
Ronda Rousey is a great attraction for her sport. I don’t understand why she would want to chance losing her life and I see absolutely no reason for Floyd Mayweather to want to help her lose it.
Yes, for Mayweather to fight Rousey would be like agreeing to fight an old man, regardless of the outcome, Mayweather loses. The worst part is that, assuming he is smart enough to have no part of this, there will be idiots claiming he is afraid to fight her.
