Another FT Lane Question

[NCAAREF]

Not sure what you mean by lane space 2 and 4. There are only three lane spaces available on each side of the key. By NCAA Women's Rules, the bottom lane spaces on both sides MUST be occupied by the defense. The next lane space MAY be occupied by the offense ONLY, and the last or top lane space MAY be occupied by the defense ONLY. This prevents any switching except for spots between teammates.
