I never said that leaving the court for an unauthorized reason was legal under NFHS rules. That is a player technical foul according to 10-3-3.
I was responding to the original post which describes a player saving a ball from going OOB, but then going OOB himself, subsequently returning to the floor, and being the first player to touch the ball. There is no question that this play is legal under NFHS rules.
This play was also legal LAST YEAR in NCAA games, but I believe that the NCAA is calling this a violation this year. Although, I disagree with that interpretation. The rule change should have been clearer and only should apply to those situations which would have been a technical foul last season. They shouldn't be negating good plays, only those that confer an unfair advantage.
There is a bulletin on the NCAA website too on this change, but it is not helpful for the saving the ball example. Here's the link:
