From my pregame conference: Stay in your primary. Seldom should we have four eyes on the ball. It must be obvious to come out of your primary. If something is there that really needs to be called, call it.
Some, on this Forum, regarding this issue, have used the phrase, "Don't call the ants. Call the elephants".
Other metaphors? Felonies and misdemeanors; and apples and oranges. Wait? I'm being told ... What? Doesn't apply? Just elephants and ants; and felonies and misdemeanors.
