Question about a junior girls play

[narwhal]

So... since team mates are allowed to touch each other and, in our league, back court defense is not allowed I'm wondering about something that I'm not sure is legal or not legal. The players in possession of the ball ran down and lined up on the half court line, joined hands but were facing the other teams basket. Because back court defense was not allowed the defending players were not able to cross the half court line to get in front of them. The guard dribbled into them where they formed a ring around the guard and closed hands together... there was really no way to reasonably break the ring without drawing a foul but i couldn't think of any reason why this technically wouldn't be allowed either. Anyway it was 11 year old girls so, there's bound to be some silliness anyway. Thoughts? Opinions?
