Try these:
1) 4/10, A-40, time and score irrelevant.
A11 legally punts the ball from the A-32. B55 blocks the ball which falls to the ground at the A-34. While the ball is loose, end A88, untouched, steps out of bounds to avoid an opponent. A11 recovers the ball at the A-35, and runs laterally. A88 steps back into the field of play at the B-40, and moves toward the near hash mark. At the A-35, A11 throws a pass to back A20. A20 catches the pass at the B-35, where he is immediately tackled, and the ball is declared dead. (Note: No originally ineligible Team A player has been, or is, more than three yards beyond the NZ when the passed is released.)
2) 4/10, A-40, time and score irrelevant.
A11 legally punts the ball from the A-32. B55 blocks the ball which falls to the ground at the A-34. While the ball is loose, end A88, untouched, steps out of bounds to avoid an opponent. A11 recovers the ball at the A-35, and runs laterally. A88 steps back into the field of play at the B-40, and moves toward the near hash mark. At the A-35, A11 throws a pass toward A88. Just as the ball is arriving to A88, B99 grabs and pulls A88 down, restricting A88 from reaching for the pass. The untouched pass falls to the ground. (Note: No originally ineligible Team A player has been, or is, more than three yards beyond the NZ when the passed is released.)
We could go on and on, like having A11 make a second kick instead of a pass, or A88 touch the pass before any Team B player. But, in both cases above, officially, A88 has made an illegal return to the field of play, even though the kicked ball failed to cross the NZ. In the absence of the kick that failed to cross the NZ, A88 would have done nothing wrong in either of the two given examples. Instead, B can have the penalty at the previous spot, and repeat the down (example 1), or decline the penalty and take the ball at the previous spot (example 2). (Note: No DPI in 2), because A88 wasn't eligible, after being OB voluntarily.)
Maybe an unintended consequence. Easy fix: No Team A player who goes out of bounds during a scrimmage kick play in which the legally kicked ball crosses the neutral zone may return inbounds during the down.
