Goal line cameras will improve the game

Goal line cameras have tremendous potential, but only if they are incorporated in a way that doesn’t stop the game.

Here is my suggestion:

In America’s NFL there is a booth in the stands where questionable calls are reviewed.

It’s possible to put such a referee in a booth with a set of 3 or so screens with different angles of the goal line.

Similar to how the referee looks to the linesman for offside before he awards the goal, he can communicate with a booth quickly, maybe by putting on an earpiece to get confirmation of the ball crossing the line.

In this way we don't slow the game, a goal is really a goal, and to assure this, it could get reviewed after the match for accuracy.

One problem.

The reason Rob Lewis didn't give That Goal in Spurs-United is because he wasn't standing on the goal-line. You cannot make an accurate decision on whether the whole of the ball has crossed the whole of a line unless you're standing on it (there's an experiment you can carry out with a ball and a line I'd be only too happy to tell you about). Therefore, each of these camera angles would have to be exactly level with the goal-line. Taking into account the limitations of stadium architecture, could it be done with cameras giving a clear enough view to see anything?

There's also a rather pedantic point about replays in the NFL. Reviews of plays are not done by an official in the stands, but by the on-field referee with the aid of monitors at the side of the pitch.

I was actually thinking of putting cameras in the goalpost, similar to the in car cameras seen in Formula one.

The technology is there...

Once camera at the bottom of each goalpost and one above in the center, something like that. That way the camera is always angled on the goal line and would eliminate the chance of players being in the way.

Oh, and the NFL, I have not seen it in years, but at one point in the past they were in a booth.

Still the possibility of players getting in the way of all three cameras. Also, there may be technology to allow cricket to put a camera in a stump and for F1 drivers to carry a camera above their heads, but in neither case is the camera designed to sustain the impact of a ball hitting it very hard. I'd want a guarantee that each camera could sustain the impact of being hit very hard by a ball, and that it wouldn't affect the profile of the goal (so that a ball striking a camera wouldn't behave differently to a ball hitting any other part of the post).

Personally, I think that if there is going to be technology for ball over the line, the best bet is going to be along the lines of balls with technology in them (either a chip in the middle of the ball that won't move, or an inner skin) and a sensor placed far enough behind the line to detect when the whole of the ball crosses it. That would give an instantaneous decision: either the system is triggered or it isn't.

You make a good point, I also support the technology you mention in the ball.

There would be occasions of players in the way, but consider how often a goal like situation would happen and also how often within that situation all 3 cameras were blocked by players.

The cameras in F1 cars take serious punishment, if you notice they almost always still transmit during and after accidents.

Another idea I had was to have the a line drawn (like we see when the ref measures the wall) on the field during free kicks so we know always its 10 yards and no more of that silly jostling.
