Hi Ross, I'll be fine once i get the first one out the way I'll be fine. I got super nervous before my first kids game and that was under 13, seems funny I was so worried aabout a bunch of 13 year olds.
Its still a DOGSO offence if it is heading towards the goal, regardless of wether it is deliberate or not. That is my opinion on it.
If it was a deliberate DOGSO offence, then yes I would also sanction them with a Red.
The reason I would give a penalty, even if it wasnt deliberate, is down to match control, especially at park level, because if that ball doesnt enter the goal after hitting the hand of a defender, and you allow play to go on, you're opening yourself up to a world of problems.
