It's because Jason Collins isn't sh*t. He is a career journeyman & 12th man on the bench. Before his announcement, his only claim to fame was being part of one of six sets twins to play in the NBA. His career was most likely over before he made this announcement. He only made this announcement so that he can financially capitalize on it now that his career is over.
The media needs to start asking the tough questions.
There are no tough questions here, you dunce. Everyone knows Collins is a career journeyman, he's admitted it himself in the interview. He's still the first NBA player to come out of the closet, he'll most likely be followed by many more, and if he ends making some coin off of this, good for him for spotting the opportunity.
