If a ball is kicked towards the goalpost, breaks mid-air (or during the kick) and only a piece gets into the goal (crosses the line) - is the goal going to be accepted?
There are some edge cases for this question:
- what about two or more pieces flying towards the goal (and therefore making it difficult or impossible to stop them)?
- if the integrity of the ball must be conserved - does "integrity" means "exactly one piece"? (could it be flat for instance?)
In other words: is there a clear standard for a ball to be accepted for a goal?
My son asked this question this morning and I could not find anything which would even be close to an answer (there were discussions about the net, which is less controversial)
