    What are the two 6 inch lines just toward the baseline from the free-throw line and inside of “the paint” for? they seem to be aligned with the edge of the free-throw circle closest to the baseline. What rule are they intended to be associated with?
    Thanks, Paul

      We have done extensive research and are finding that these lines are not consistently used throughout the entire sport of basketball (high school, college; women’s, men’s; etc.), and I’m not showing a specific name. If I happen to come across this I will pass along the information. Great question!
