His whole brand is being over the top which is why he is known as "Money" Mayweather. While it is insanely wasteful and ridiculous, his brand is worth so much because of the opulence he projects. Why did a ton of people pay so much to watch him fight... cause they want to see a cocky mofo get knocked out. But then again he is just laughing all the way to the bank once again after another win. Cannot deny he is an incredibly skilled fighter, even if the fight was boring.
Would I do it.... noooooo. In some strange way, does it make him more money to do insane things such as this... most likely.
