I hate to play devils advocate, and I know this will make me unpopular, but... I think in this case the officials were correct. In fact, I was 100% convinced it was not a goal when I saw it live. Unlike the two flakes on SN1, I don't need 10 different slo mo replays to realize I still don't have a clue lol.
First of all in the picture, there is a parralax error involved. secondly, you're talking about "green between line and ball", when in fact, the whole ball should be taken into account, not just the part of the ball in contact with the ground. If any part of that diameter is "touching" any part of the white line, then its not a goal.
