If I run the Charlotte Bobcats or any other NBA team, I don't make room on my roster for Jason Collins because he's gay. I don't exclude him from my roster because he's gay.
If I think he can help my team, and I can afford him, I bring him to camp. If I don't, I don't.
What Collins did, coming out publicly, required courage. It's a testament to how far society has evolved that support for him, especially from other athletes, has been overwhelming positive.
But he's a journeyman with a particular basketball skill set. Maybe he makes a good team better.But he'll have little impact on a bad team.
Some seasons the Bobcats collect journeymen. They don't need any more.
