I’ve sort-of gotten spoiled and I am sure others have too. The imposed black scrimmage line and the yellow 1st down line sure help the fans keep perspective, I guess that’s what it’s called.

As I watch a game on TV, I can’t help but think that it’s a shame they can’t put a light on the field that would do the samething.

I’m sure it can be done. However, there are at least 2 conceivably problems, maybe 3. Any time a player got between the projection and the ground, the line would show on the player, not the ground. I suppose the question might also come up, do the refs use the projected line or do they try to ignore them.

Then too, if the player fell, looking into the light, it might cause eye damage or perhaps temporary blindness. I guess they will have to wait just a while longer for the technology. Eventually, maybe all the lines will be protected. That would help when the field is muddy or covered with snow.

Then too, no 1 team could use it unless they all did.
