I've never played a pick up game with a girl where the girl was the worst player or played worst on the court.
If nba basketball was predicated on athleticism alone I'd say no, but it's not.
If all the guys weren't allowed to have steroids or HGH and you had a phenomenally athletic, excellent shooting, excellent passing, dedicated defender, highly coachable on a smart team with a good coach I think she could make a contribution. You couldn't leave her open.
If you had guys like Mugsy Bouges playing for many years in this league and guys that are slow and fat a perfect woman I think could do it.
Also there's one other thing. There are other sports (not as athletic necessarily) where women can compete or exceed. I asked an excellent high school golfer that got a scholarship to BC I think if he could beat Michele Wie, and he was like, "No. None of us can". I asked him if he thought maybe she were on roids or something "And he said maaayyybe, but I don't think so"
Ever seen a woman fencer fence a good male fencer? There are highly rated male fencers that can't touch some of the best women.
I'm just saying it's not against the laws of physics, and with the success of Title 9 I see this as a possibility in my life time.
Also it would take the right team. If you just put a girl on the Clippers or something you're screwed. But if you put her on a veteran team and they know how to help on defense and draw a defense in to get her a clear shot and they're unselfish it can work.
If you put Diana Taurasi on the Celts tomorrow and they go out to play the Clippers or the Bobcats and she gets 20 mins and the Celts want to win that game there is no way they lose that game.
