A couple of measures that should be taken against my friend from New Jersey:

1. Opposing coach should alert the ref prior to the match that this little trick has been used before. Be on the lookout for it and give the captain a yellow and the coach a red.

2. If the ref should notice this, wait until the ball is relatively close to the offending team's goal before blowing the whistle and carding the captain & coach. The restart will then take place in a very dangerous area (could result in a goal from the free kick).

Kids play sports because they find it fun. Eliminate the fun and soon you eliminate the kid.
