Why couldn't they have that type of discussion?
I don't have the women's NCAA rulebook, but the 2019 one for the men which I have downloaded has a rule about fingernails.
Art. 5. Equipment that could cut or cause an injury to another player shall be prohibited, without respect to whether the equipment is hard. Excessively long fingernails shall be prohibited.
I think another problem which isn't mentioned much is the long hair. When it is braided it can whip around and hit other players in the face or eye. I would be shocked if there were not a rule addressing what can be woven into the hair, hairclips etc... That and the fingernails are safety issues.
On the other hand, last I read, the NBA did not have a fingernail length rule and some players would intentionally grow them sharp to cut other players with hand checks etc... I found that surprising and would like to see that verified by another source before I fully believe it.
I don't know how long any particular player's nails are on our team, but I will say that they could affect more than just catching the ball since the follow-through on a lot of shots rolls off the fingertips. They can cut other players or get caught in opponent's jerseys. If you are serious about the sport, you will keep them at a length that does not interfere with play. But that length might be open to interpretation as you can see from how vague the men's rule is.
