Girls V 3 on 3

[BillyMac]

Thirty years ago, when Title IX kicked in, our school started a girls basketball team. We had a student-faculty game that year. One of our female faculty members never went past the division line. She told me that she only played defense when she played basketball in high school.

I've heard that, under some rules, one player, I believe, called a "rover", was allowed to play both offense and defense, and could cross the division line???? Not sure though?????
