We all agree that the play ends 4th and goal at the B-1 with no touchdown. What I'm asking is which rule produces the spot.
8-2-1-VII has the runner stepping on a) the goal line, b) stepping on the sideline; neither apply here.
5-1-3-a: The most forward point of the ball when declared dead between the end lines shall be the determining point in measuring distance gained or lost by either team during any down.
AR 5-1-3-IV: A4, with the ball breaking the plane of the 50-yard line while in his possession, dives over the 50-yard line, which is the line to gain for a first down. He is knocked back to Team A’s 49-yard line, where any part of his body except his hand or foot touches the ground. RULING: First down at forward progress spot (Rule 4-1-3-b).
No issue with that.
4-2-4-d exception gives progress as the position of the ball as it crosses the sideline, but only if they are airborne as they cross the sideline, or a striding runner (also crossing the sideline); in this scenario , the runner is completely inbounds.
Totally fine.
But in this scenario, the most forward point of the ball in this scenario, isn't at ANY yard line. It's in no man's land - it's past the goal line extended, (which we known is not extended for scoring purposes in this scenario, just using it as a reference point here). 5-1-3 can't apply, because we obviously can't put the ball in the EZ, even though it's technically past the goal line. We can’t use 4-2-4-d because the runner did not cross the sideline, he was completely inbounds.
What specific rule says when a runner is down inbounds, with the ball extended out of bounds, the spot is where the runner is at?
