What I would like to see is a fourth official assigned to games that works the clock.
They have it in football, why not basketball???
He could be a beginner or 'new' official who is trying to get experience. Put him in the crew for the night, he gets to sit in with the crew for pre-game, ask questions and basicly get 'on the job training'.
Or - older, seasoned officials who want to stay around the game but are past their prime could do this job as well.
It would be an excellent training opportunity with minimal expense involved.
