Way to intentionally ground legally?

[CT1]

"SECTION 31 ART. 1 . . . Passing the ball is throwing a ball that is in player possession. In a pass, the ball travels in flight."

What you described doesn't meet that definition, at least in my mind. I would very likely rule your play a fumble.

I guess I see this as similar to a play where a runner, in the process of being tackled, intentionally "fumbles" the ball forward to a teammate. The term "throwing" seems to apply equally to both cases, and the ball certainly travels in flight. If we rule that play an (illegal) forward pass, then I'd say we should rule this a forward pass and therefore intentional grounding also.

I think it would be as easy to make this as much a throw as is a shovel or chest pass as commonly used to make a short forward pass to a receiver in the backfield. It should be very easy to, for instance, face the right sideline and clearly pass the ball forward across the body with the right hand to knock it down with the left. I don't think anyone's current code makes that a fumble, nor do I think any of them make it an illegal/intentionally incomplete/intentionally grounded pass.

I suppose you could get fancy with it by passing it from behind your butt thru your legs to your other hand, but that might be USC for...uh...making an unnecessarily flashy move? Kind of a taunt?
