The 37-year-old has joined the long list of people interested in buying the Los Angeles Clippers, if the National Basketball Association franchise ever goes on the market.
"The Clippers are unbelievable. Of course, they've got the best color in the world: Red, white and blue. And of course I have a place in LA and who don't like the Clippers?" Mayweather told CNBC on Friday. "Me and my team, you know, we're ready to go. We're ready to make it happen if it's possible."

Several billionaires and business tycoons have voiced their interest in purchasing the Clippers, just in case disgraced owner Donald Sterling decides to sell the team—or the NBA's 29 other owners force him to do so. The uproar began after Sterling's racist remarks, which were recorded by a friend and mysteriously surfaced over the weekend, prompted NBA commissioner Adam Silver on Tuesday to ban him from the NBA for life and slap him with a $2.5 million fine.

But Mayweather, who considers Sterling a friend, spoke up for the embattled NBA owner. Mayweather only had praise for his interactions with Sterling.
"Donald Sterling has always been respectful and nice to me. You know, I can't really speak on anything else. I can only talk about myself and his relationship. You know him and his wife has always been respectful to me and always treated me like a gentleman," Mayweather told "Closing Bell."
"Last time I checked, you know, in this country, it's freedom of speech and if I cannot be anything, I can be honest. (Sterling's comments) in recording, that may not have been right, but I'm only going by how he has treated me."
On Saturday, Mayweather will fight Marcos Maidana on pay-per-view TV network Showtime.
