NBA player Jason Collins has disclosed he is gay, becoming the first openly gay male athlete who is still active in a major U.S. team sport. In a Sports Illustrated cover story, Collins writes: “If I had my way, someone else would have already done this. Nobody has, which is why I’m raising my hand.” Collins’ move comes years after numerous female professional athletes have made similar announcements, including tennis champion Martina Navratilova, who tweeted Monday: “Well done Jason Collins- you are a brave man…1981 was the year for me- 2013 is the year for you.”
