Exception: It is not a foul when the passer, who is or has been outside the
frame of the body of the normal tackle position toward a sideline, throws
the ball so that it crosses the neutral zone or neutral zone extended (Rule
2-19-3) (A.R. 7-3-2-IX).

This question was asked by a fan last week. The quarterback, outside the tackle box, throws the ball away to avoid the sack. The ball crosses the sideline two yards behind the line of scrimmage, and lands out of bounds five yards beyond the line of scrimmage.

Is this intentional grounding? What is the "neutral zone extended"?

Rule 2-19-3 states: "A legal forward pass is beyond or behind the neutral zone where it crosses the sideline."

So it seems to me that this IS intentional grounding. But I'm not 100% sure on this. Both times I've explicitly seen this the past two weeks, intentional grounding was not called.
