With all due respect to Brittney, she simply doesn't have the size or athleticism to compete meaningfully with men. Lots of male players are 6'8", but they have way more muscle and ups. Griner isn't 200 lbs. In the NBA, she'd be a small forward, but she doesn't have the handle or range to play that position.
Someone like Maya would be a little more interesting competing with men playing PG. And I still wouldn't recommend it.
Just as I never thought Floyd Merriweather should prove himself by fighting one of the Kitchkos, I'm happy with women not trying to compete with men in basketball.
