3 ft arc.....NOT - let them play - I don't see this as but something to get upset at the refs about.....even in the NBA
The three foot arc has nothing to do with "letting them play" or not. It shouldn't change the number of calls, it simply forces the referee to call a "block" when the player is too far under the basket.
Women's 3 Point Line - ALL for this....People who watch the Women's game know they can shoot the 3 ball just like the men.
Makes the court alot cleaner for the refs....not so many lines on the floor.
I've definitely seen them shoot the ball like the men, but I haven't yet seen them make the shots like the men. 
This discussion got me wondering, so I went to the final NCAA stats for the past season for top ten leaders in 3 pt shooting percentage. Below is what I found. Not definitive of course, but it seems to support an argument that, at least for the best of the best, the differences between the men and the women exist but aren't that great...interesting!
