Oscar Robertson is happy to see athletes using their platforms to fight injustice but wants to see more.

While speaking to reporters late Monday after accepting the Lifetime Achievement Award at the 2018 NBA Awards, the basketball legend opened up about the social issues leaking into the sports world and called out white athletes for failing to step up.

"I think that as people evolve, and things are changing so much in the world with social media and whatnot, these people are young people who have families," Robertson said, via ESPN. "They've seen some injustice in the streets or wherever it might be, it might be almost anywhere, and they're stepping up. But the only thing that really bothers me is, where are the white athletes when this is happening?

"This is not a black athlete problem. You see injustice in the world. It's all around you. Just because LeBron steps out, I'm glad he does. I hope some other players — because this is what they believe — I mean, what do you want players to do? Shut up and dribble? I think it's time for them to say what they want to say about life and about politics and things about the street and whatnot. And about education.

"There are a lot of players donating money back into different colleges. But it seems that what we have today is a system where you don't want players to say anything at all."

Robertson, a former head of the NBA Players’ Association, highlighted LeBron James and Stephen Curry's outspoken involvement and asked white athletes, particularly in the NFL, to join them.

"Years ago, [athletes] didn't say anything because they couldn't say anything," Robertson said. "But now I hope they all, the whites and the blacks, get together. Even with the football."

Robertson, 79, was named to 12 All-Star teams and earned MVP honors during his NBA career from 1960-1974 with the Cincinnati Royals and Milwaukee Bucks.
