Soccer Throw In Position

[CecilOne]

Thanks, I heard about that, but apparently no one knows of a similar rule or interpretation in NFHS.

The concern with being within a yard back is to prevent an angle that allows the ball to cross the line elsewhere, concealment behind the bench (10 feet in NFHS) and other trickery. So in NFHS, as long as we judge that the ball entered where it went into touch without deceiving the defense, the throw in rule is satisfied.
