10-1-2 cover it?

[Camron Rust]

As long as the players appeared to be eligible, there is no reason to oppose the coach adding them to the roster. It is up to the team to put eligible players on the court. If they don't that is largely their problem.

By "appeared to be eligible" I mean of an appropriate age/gender that they could possibly be on the team and I would only oppose any exception from a liability perspective. You wouldn't want a 9 year old playing with 14's and 15's no matter the situation. The physical differences would just be too great and the risk of someone getting hurt would not be acceptable.
