Making Calls out of your primary.

[just another ref]

Comments of the casual observer about officiating often have little or no significance to the officials, but in this case I think they do. The casual observer may know nothing of areas of primary responsibility, but a "long distance call" tends to attract a lot of attention. "My gosh, he called it from all the way across the gym!" What's wrong with the other guy? It was right in front of him!"

There are exceptions to everything, but:

If you make this call and get it right, it tends to make the crew look bad.

If you make this call and get it wrong, it is pretty much unforgivable.
