You are suggesting to put wires underneath the grass right? That would get exposed every 1-2 games. Not practical. But still a REALLY COOL IDEA.
I do understand what you are suggesting with the goal posts. The thought has crossed my mind. The problem with using a laser in determining field goals is, can the laser determine conclusively which way the ball would bounce off of the upright? Why not just raise the uprights another 15 to 20 feet high?
greenie has talked about this with the foul lines/poles in baseball, and the strike zone. it seems very practical with foul lines and seems like with goal posts would be too. red mentioned ipad. someone tell apple there is money in it and we will have it by next season.
