"Imaginary" 3 foot restraining line? NFHS Throw Ins

I am further torturing myself to recall if this leniency applied to 'spot' throwins or only to 'run the endline' situations.

Or it could be just a figment of my overhyped imagination.

Help me out Billy Mac, MTD Sr., Nevada!!!

If teammates of the inbounding team cross the line on a spot throwin, it is a violation just like the boundary of a typical throwin.

If the teammates of the inbounding team cross the line (temporary or not) on a throwin after a score, the defensive team may not follow or they have violated.
