A snaps the ball at their own 40 yd. line. QB scrambles in the pocket momentarily. Meanwhile, A1 runs a route along the sideline. He steps out of bounds on his own at the B 30 and returns in bounds at the B 28 where he catches the pass thrown to him.
As I read the NFHS Casebook, a similar play in SIT 9.6.1A indicates we would enforce this from the spot of the foul-which is where he returns in bounds (B 28). Some other guys in our association indicate because this is a loose ball foul, we are going to penalize it from the previous spot as the offense should not benefit from any positive yardage when they fouled during the down.
How would you enforce it and why?
