20. Jason Collins (NBA)
Jason Collins played professional basketball and at one point played a fairly large role for the New Jersey Nets. That was a distant past, when they were actually good. During those years, you never would have known that Jason was gay. It wasn’t until 2013, when he did an interview with Sports Illustrated, that he came out of the closet. What’s strange is that coming out seemed to hurt his career because he was never really heard about after that interview. Keep in mind that professional basketball teams are smaller than teams in most other sports. This means everyone on the team knows each other rather intimately.
