Jason Collins, who played 13 seasons in the NBA as a center-forward, died Tuesday at 47 of glioblastoma, an aggressive form of brain cancer.

Despite playing for seven NBA teams and starting for the then-New Jersey Nets (now the Brooklyn Nets) during their back-to-back NBA Finals runs in 2002 and 2003, the most memorable part of Collins’ legacy will be that he came out as gay late in his penultimate NBA season.

“I didn’t set out to be the first openly gay athlete playing in a major American team sport,” Collins wrote in an April 2013 essay for Sports Illustrated. “But since I am, I’m happy to start the conversation.” Unfortunately, more than a decade later, the conversation Collins started has largely stalled. Aside from former NFL player Carl Nassib, there has not been another openly gay active player in the NBA, NFL, NHL or MLB.

Openly does all the heavy lifting in that sentence because the likelihood there hasn’t been another gay player among the thousands who’ve played in those leagues since Collins’ announcement — or among the many thousands who played before him — is nil. Therein lies the tragedy. Despite the courage he showed by coming out of the closet, there is still a closet in male professional sports.

That’s why NBA Commissioner Adam Silver’s response to Collins’ death Tuesday is a bit awkward. He said in a statement that “Jason Collins’ impact and influence extended far beyond basketball as he helped make the NBA, WNBA and larger sports community more inclusive and welcoming for future generations,” and that he will be remembered for “breaking barriers,” but the NBA doesn’t appear to be any more inclusive and welcoming, and the barriers seem just as visible as ever.

The statement is even more glaring given its inclusion of the WNBA, where players have fought for higher pay that still doesn’t rival the men’s game, but where players’ sexuality has largely been a non-issue.

The NBA barrier continues to exist despite all the professed support from NBA players, coaches and legends when Collins came out in 2013. “This is a great day for the NBA,” Charles Barkley said. “Proud of @jasoncollins34,” Kobe Bryant wrote. “Don’t suffocate who u r because of the ignorance of others.”

And LeBron James said: “I think it’s very noble on his part. I think it’s a strong thing to do, and I think as NBA players, we all offer him our support.”
