Several years ago, San Francisco 49ers quarterback Colin Kaepernick made waves around the sports world for his decision to kneel during the national anthem in protest of racial inequalities and injustice in the United States and in the NFL. And even though it’s been six years since his protest, he doesn’t think there’s been much change in the NFL.

During an interview with NPR on Tuesday, Colin Kaepernick was asked if he felt that the NFL has changed for the better since his protest. And he had a pretty blunt message for the league in response.

“I haven’t seen any substantial change,” Kaepernick said in the NPR interview, according to Fox News. “I think there is a lot of work to do on that front. Obviously, not playing and being out of the NFL for six years is an indictment on where they are currently at. So I wouldn’t put them at the forefront of goodwill and best of intentions in how they operate.”

Kaepernick has not played in the NFL since the 2016 season. After he went unsigned following his protests during the national anthem, he accused NFL owners of blackballing him from the league. After the two sides settled, he held two tryouts in front of NFL scouts but was not given a contract with any team.
