What is Mayweathers gain to carry on Boxing?

Mayweather isn't carrying boxing. He's carrying himself.

He's destroying boxing.

Look at how boxing could have benefited through him and 50 cent.

But instead, 50 cent, said, let's start if off with the Pacquaio fight.

Floyd ran.

Floyd doesn't give a **** about the sport of boxing.

Fighters like Floyd RUIN boxing.

Just like he said he would fight Alvarez but was too scared to sign the contract.

Put your money where your mouth is.

Be a man.

Sign the contract.

 

double edged sword...

boxing is not a mainstream sport, yet when floyd fights it makes headlines around the world

floyd (and pac) are bigger than the sport - if boxing wasn't so fragmented that wouldn't be the case

 

$$$$$$$$$$$$$$$

 

I think you hit the main two reasons squarely: his spending habits and his ego.
