Over and back is now a rule. In fact conversely, many women’s basketball rules have prompted men’s basketball changes too. The women’s game has always had a shot clock , in fact a 30 second shot clock since the early 70’s. Men didn’t even have a shot clock til 1985 and it was 45 seconds not changing to the 30 seconds women’s shot clock till 3 years ago or almost 50 years after the women. The women’s game is now 4 ten minute quarters vs 2 twenty minute halves that the men use. They also reduced media timeouts to one a quarter and foul shots after committing 5 in a quarter. The men studied but voted down going the same way. Women are also selectively experimenting this year using the international women’s 3 point line of 22 feet 1 and 3/4 inches vs the current 20 feet 9 inch line which is the same as college men’s. That’s why you no longer see multiple lines on college courts. So it may change if agreed upon after this study so the women’s 3 point line could be longer than the men’s thus more lines on the court again.
There are very few differences any more. The women’s game has been much more progressive in looking at the rules. Men’s college game has historically hated change , a reason it took so long for even using a shot clock and till just 2015 to lower it to 30 seconds, what the women had used for about 45 years. Men may look closer at using the international 3 point line and using 4 quarters again in the future if it works out well for the women. The women use the NBA model much closer than men’s college basketball.
