It's safe to say that WNBA rookie Brittney Griner has already changed the game of women's basketball. Yes, the 6'8" center dunks. But she's also among the highest profile openly gay athletes in the country.

Griner made her professional debut over the weekend when her Phoenix Mercury lost to the Chicago Sky. She dunked twice, and it's such a big deal that someone made a slow-motion video out of it.
