This is an interesting concept IMO. It would tell the ref when the ball crosses a a first down or goal line. It wouldn't be able to tell if a player's knee was down at the time the ball crossed the line. It takes some of the guesswork out of getting calls correct, but it is by no means a perfect solution. It would be a good addition to the instant replay system.
