Question:  What do goal lines, field goal posts, first downs and out-of-bounds punts all have in common?  

Answer:  With respect to football placement, in many situations, they still involve some level of human guessing. 

Instant replay has helped the game immeasurably.  I dare say that when applied to past NFL history, that technology would have resulted in new winners, losers and champions.  So we know that technology helps to bring certainty, and I now put forth the idea in an entirely new way.


How many times during a football game does a referee guess at:

  • The exact spot of the ball, with respect to forward progress
  • If the football broke the plane of the goal line
  • Exactly where an out-of-bounds punt crossed the sideline
  • Whether a field goal was inside or outside of the post

Next, create a mapping system, for locating the ball within the field.  GPS doesn’t work indoors, due to bouncing off roofs walls and other structures – and it is not very accurate.  Therefore, we would need to utilize a grid-based system, where a dense network of low-range (ultrawideband) receivers would be planted into the playing field.  Techniques used within this system would include localization using Time Difference of Arrival (TDoA) – also known as ‘multilateration’.

This system would be mapped to a specific computer-based image of the football field, passing on location results as pixel points on this field map.  So when the any transmitting chip, on either end of the football breaks through  and pass on location results as exact points on this image.  This would also include receivers placed on the tops of field goal posts.  Effectively, the entire field would be ‘covered’ by an electronic grid network.

So now:

  • The punter shanks the kick…now WE KNOW where it’s to be spotted.
  • We can be sure that within a large pile of players at the goal line, the running back DIDN’T break the plane of the goal line.
  • The tip of the ball DID in fact reach the first down marker with forward progress on the pass.

This is the beauty inherent in having specific location points of the football during every game.  This would optimize many of the the remaining mistakes, which are too valuable to leave in the hands, opinions and judgement of the officials.  Google, NCAA, and NFL…feel free to reach out to get this started.  My son and I will be happy to attend any and all games during testing.
