Floor Spots

[OKREF]

Just saw this..


Throw in on the endline. Team A lines up perpendicular to the endline about 5 ft off the endline. Team A is lined up so they are back to front. Team B wants to get a spot in between A1 and A2. A players don't move. Lead says they have to give a spot to B. Trail says no they don't.

7-6-5 says if they line up parallel within 3 ft of endline and are shoulder to shoulder they are granted a spot. If it is more than 3ft away from the endline, team B request is denied.

Couldn't find anything about perpendicular in the book. Any thoughts on how to handle this.
