Free throw shenanigans

[SNIPERBBB]

Issue during boys scrimmage tonight

A1 and B1 in the first and second spaces. B coach wants B1 to switch to the other side do he can be matched with A. A1follows B1 over as A2 and B2 also switch. So A1 reverses back..and so does B1.

Do we eventually have a stalemate in the middle of the lan as 4 players now have no idea where to go. B coach is insisting that they have a right to get the matchup they want.

A eventually yeilds.

If the stalemate continues, and it was already too long to me already, what would the remedy be? I don't believe there's a rule that gives B the right to the matchup they want. Player technicals would stop this happening again but probably not they helpful.
