There are a lot of moving parts to this play from Dowagiac High School in Michigan:
1. The receiver who trips and falls when the ball is snapped;
2. The quarterback who drops the snap, then plows into the line;
3. The other receiver who lingers behind the snap to receive the quarterback's desperate heave from the pile.
Put them all together and they end up looking like this:
Planned? A happy accident? Either way, it's pretty cool.
