Just a few years ago, names like Michael Sam, Jason Collins and Brittney Griner were all making headlines – pro-athletes who are LGBT on the fields and on the courts.
Since then, though, another major athlete has yet to debut with the same level of enthusiasm and energy.
What happened? And how do you get sports and sports fans to be more open and accepting of LGBT athletes?
Cyd Zeigler, creator of Outsports, says the game has already changed in his new book, "Fair Play: How LGBT Athletes Are Claiming Their Rightful Place in Sports."
"The idea that athletes are going to be rejected by their teammates and their coaches and fans just is not true anymore," he says. "The media is failing its job to demonstrate that."
Zeigler argues that most media attention is focused on issues in the locker room and the challenges in coming out, not the camaraderie and community within teams.
"In 2012, 60 percent of NFL players polled supported same-sex marriage rights," he says. "Less than 50 percent of the general population did at the time."
