Intentional Grounding or Not?

[JMN]

Mike, If I read this accurately, are you saying that A7 when he "turns around to run further back in his endzone" is facing his end line and has his back to the field of play?

I would have to be there, but if he has no vision of where the ball is going and throws it over his head (backwards) to avoid getting sacked, then I would rule that this was done to avoid losing yardage and penalize him appropriately. It may be legal according to the rules, but his intent is obvious.
