And there's no way in hell I'm going to explain to an assigner that I called a backcourt violation when the player caught the ball with backcourt location, never moved, and then proceeded to do nothing before my whistle.

I don't care what the coach thinks.

Let me ask another question.

A1 catches the ball while sitting on the floor. Both feet come off the floor for a brief moment, but the player never moves other than that. You calling a travel?

There is no pivot while on the floor.
