It was not grounding dude. You are not winning this argument. If this was the case. Why don't they call grounding when a QB throws it into the ground? They don't. You want to know why? Because they can't tell where that ball was intended to go. You really only call grounding when you can tell the intent of where the ball was going. If the DL effects the ball in anyway where the official can not tell where it is supposed to go, they don't call grounding.
