Former NBA champion Stephen Jackson joined the chorus of voices criticizing rapper Lil Yachty for referencing George Floyd in one of his songs. The rapper previewed his track on a livestream with PlaqueBoyMax on Thursday. In one of the songs, Yachty references Floyd, saying:“Put my knee up on her neck, I went George Floyd.”Floyd was killed in May 2020 by Minneapolis police officer Derek Chauvin, who knelt on Floyd's neck for over nine minutes while he was handcuffed and lying on the street.Stephen Jackson took issue with the content of Yachty’s song and called him out in a video shared to Instagram on Thursday. Jackson called the rapper's music “wack” and said it was “weak” of him to include Floyd’s name.“Trying to use his name [George Floyd] in a bar, that’s gonna make people like your wack a** music, my n****? That s*** is weak,” Jackson said.Jackson claimed rappers like Lil Yachty don’t know anything about Floyd and only use his name for “clout.”“None of y’all knew G [Floyd], nothing about him. But y’all want to say his name for clout,” he said. “Let somebody die in your family, we gon’ do a whole skit about it and see how funny it is, bro. Cut that s*** out, man.”Jackson, who won an NBA championship with the San Antonio Spurs in 2003, had a personal relationship with Floyd. The two met as children in Houston’s Third Ward and shared a friendship spanning over two decades."He looked out for me": Stephen Jackson details his two-decade-long friendship with George FloydStephen Jackson was one of the most vocal athletes advocating for social justice following the death of George Floyd in 2020.
