pet peeve - Last second shot - NCAA Men's mechanic

[Dewey1]

I have a question. Why is NCAA men's mechanic in 3 person to have the offical opposite the table make the decision on a last second shot at the end of the half or game, yet for the rest of the entire game all shot clock violation are called by the primary offical? It seems funny to me that for 59.59 sec's primary is able to handle all shot clock violation yet at the end of the game we which to opposite.

This is not a real big deal just a pet peeve. I think it makes 2 people watch the ball if the shot is out of my primary and I am opposite. It really reduces the off ball officating. I am curious to anyone else opinion.
