because if you're a real fan of boxing, you care about boxing more than about how much money somebody makes doing it
LOL whatever. Keep getting a hard-on over Floyd Mayweather's pay-checks all you want, i ain't mad at ya. Whatever does it for you.
it's not actually necessairy for a boxer to make sense or having more working braincells than Floyd to be succesful, but it is preferred. Let him say rediculous things, make stupid claims, and spend all his money. As long as he fights Pac somewhere in the near future.
