Free Throw scenario / questions

[bbodb]

Sorry for the less than direct title of this posting but this question needs a bit of set up. Here goes. (NFHS rules.)

In thinking about games I have refereed lately, I am noticing more players attempting to gain an advantage with respect to lining up on free throws.

Lining up scenario - with respect to rule 9-1-3-G

A1 is shooting a free throw and opponent B1 occupies the appropriate marked space closest to the basket.

Situation 1) B1 lines up at a 90 degree angle to the lane - in such a way that her backside (derriere) is pointing toward A2 (who occupies the adjoining marked space). B1's feet are on the floor and within the vertical planes of the marked space but her derriere is clearly extended into the adjoining space.

At this point, I don't think that B1 is committing any violation as there is no contact with A2 (so no need for any action on my part). But the plot thickens....

Situation 2) B1 does lines up the same way as described in Situation 1 except she lines up on the balls of her feet. B1's heels are off the ground and extend outside the plane of the marked space. There is no contact with an opponent.

By the rule, it appears that I should call this a violation and award a replacement free throw if the free throw try is unsuccessful. To me, this seems trifling but it may prevent future problems....

Situation 3) A2 now returns the favor and lines up at a 90 degree angle to the lane - in such a way that her derriere is touching B1's. Obviously, there is contact....

The common sense approach would seem to be just a quick word to the players to stay in their area and if they did not do so, call the appropriate violations as needed.

Thoughts please?

Thanks.
