Should lasers and electronic grids be used in football for marking ball placement and 1st downs?

Just a thought I had about making the game more reliable then a human eye that is about 20 yards away from the ball.|||Should they? Probably. Although the NFL is just NOW putting the replays in HD, kinda scary that we had home could have had a better view isn't it? Do I care if they do? No, come on yeah a "bad ref" could cost you a first down, but that same ref could spot you a first down or an extra yard when they aren't "bad". I'm all for letting it not be an exact science because you KNOW your team gets a break here and there too and at the end of the season it is pretty much evened out.|||No. Thats stupid|||The blown calls are part of the charm!!|||Maybe we should replace the players w/ robots too.|||No, when you take human element out of the game, you do not have a game.|||Believe or not I like that idea, there are too many blown calls by bad ball placement, there are enough opportunities for other bad calls in the game.|||This is not a video game. I rather trust the refs than a machine.|||That's why teams need to crush their opponents. The more lopsided the game is, the less bad calls matter. Close games is where bad calls can hurt a team. There is talk about puting a tracking device inside the ball in a few major sports and they already have the technology to do it, but it adds after game talk to have bad calls and that's probably what the owners want.|||No. Clearly this is overkill.





However, I've always found it amusing that when the ball is down very near the first down, they go to great lengths to bring in the down markers and precisely measure to the millimeter, but they just eyeball it when SETTING the down markers on a change of possession or after a first down.
