See stopping the game for that is fine IF the ball does cross the line, if the ball doesn't cross the line however what happens?
Some of these ball / line decisions are replayed time and time again before people come to a correct decision, it can take an age
What happens if the ball doesnt cross the line, its still in play but the ref will have stopped the game to get a decision, how does the game then restart? The obvious answer would be a drop ball as no one has done wrong. Where should the drop ball take place? In the centre circle? well thats not fair on the attacking team, they've lost ground. At the penalty spot of the correct box? Well thats not fair on the defending team, to have to potentially defend again something which apparently they'd already succesfully defended.
Se the thing is once the technology and the ability to use it is in place, refs will rely on it more and more, even for cases which they were 95% sure anyway.
Nah give me human error anyday. What we need is better refs
Let's say that that Hull game determined whether or not Villa finished in fourth place, and they WERE awarded a penalty, which was converted, putting Villa out of the Champions League.
Would you still be steadfastly against it?
