It occurred to me how ridiculous it is to see 6 guys managing a hunk of chain on two sticks to determine if the football has moved 30 feet since the previous first down.
With the inexpensive technology that is easily available today, the positioning of the football after each play should be (sic) "child's play". A transmitter could be sewn into the lining of the nose of the football and tracked to within a micron of it's previous position on the field. I'm thinking that laser monitors, positioned at each corner of the rectangular field could determine at exactly what point the ball stopped moving forward (with subjective assistance from the officials), or when the ball went out of bounds on the sidelines. This would especially be helpful now that the trend is for the runner to extend the ball out past where they are actually running out of bounds. The guys with the chains wouldn't have to struggle to negotiate the sidelines after every play. All that would be needed is the down marker.
Essentially, measurements for first downs would become unnecessary. Once placed , the exact position of the ball from the previous first down would already be established. A simple signal to the referee allows him to make the first down call and continue play. This would especially be helpful now that so many teams, like the Eagles, are using the no huddle, hurry-up offense.
This would also be crucial at the goal line where so many touchdowns are difficult to call because so many bodies are blocking the view of the refs. Officials would know if the ball made it over the goal line because it is a predetermined, fixed position on the grid, and the computer will know when that position has been reached by the ball.
All in all, this technology would allow the game to flow more naturally without needless interruption and less commercials. The perfect reason for not introducing it, right Roger?
