I always laugh at the ridiculous ceremony of walking out with "the chains" to measure whether the runner made it or not. It creates this illusion of precision which is so far from the truth. There's the error in seeing where the ball was when the runner was "down", plus the error made as the line judge walks in from the side, plus the error when the ref places the ball, plus the error of where the chain link is grabbed for anchoring, plus the error in whether you bring the chains to the exact perpendicular to the ball.

Will we ever see a system where sensors in the ball tracked by GPS will tell us if the ball crossed the end zone? Or that the ball placement results in a 1st down?
