Floyd Mayweather was courtside for last night's pivotal Clippers vs. Mavericks game ... but before "Money" got to the arena, he was handing it out, blessing three homeless men with $30k!
Our sources say Mayweather was leaving the downtown L.A. Ritz last night -- headed down the block to Crypto.com Arena for game 5 -- when he saw several men on the street.
We're told Mayweather began talking to the guys, and decided he wanted to help ... so he busted out his backpack, and blessed each guy with 10 racks.
