How about this version:
Team A is losing 35-28. Following an incomplete pass on 1st down, there are 4 seconds left in the game when A snaps from the A-48 yard line, 2nd & 10. The QB in shotgun throws a 1-bounce backward pass to WR A-80 who has backed up some 10 yards behind the LOS and is directly in front of the B bench. By now the game clock reads 0, and most of the Team B sideline starts streaming on to the field. There has been no whistles and the entire crew is still officiating a live ball play.
A-80 who is still just standing there with the ball thinking that it's an incomplete forward pass has the QB screaming at him to throw the ball, and with literally dozens of B "non-players" right next to him, finally realizes that the ball is live, starts to attempt to throw the ball downfield as he is finally tackled by B-75, who is a legal player who was in the game at the snap.
There are 20+ B "players" and most of B's coaching staff and no A non-participants on the field when the whistle finally sounds. What do we have?
