I've thought for a long time that generally the ball stays in play a lot more often than people think. Its the whole ball over the whole line. Thats why players are allowed to take a corner where only a little corner of the ball is overhanging the quadrantIt's not been shown on the TV, yet.
Aye, now I've seen that angle I would change my view and go there are two contrasting angles, so with a 50/50 split go with a goal. It's not an easy one.
But the authorities aren't helping themselves because, as mentioned above, the top view still hasn't been publicly shared, so people are basing it on one view.
