Brainstorming - if the players wore gloves and pads on the inside of the forearms that both had extremely low voltage across them, the chips in the tips of the ball could close a circuit while the ball was being carried. We might be on to something. If only GPS were precise to the inch level...

Even then, there are issues. How could you tell when the player is down? How do you tell the exact moment possession is gained (or lost)? After all, there are plenty of times when a player might have multiple points of contact with the ball before control is gained.

I'm not opposed to the crazy yellow line gizmo, but I'd think putting sensors in the ball would be a mess.
