I get that officials do not want to throw a flag every play. It bogs the game down and ruins the enjoyment of the event. Officials are like the soundtrack of a movie. They should be there, but you hope they are not noticeable.
Maybe he meant that his hope is that violations do not occur during the game.
If they do, however, I think the official has an obligation to call the penalty. I understand that if DPI happens in the far corner of the end zone against a player that could not have possibly caught the ball, the ref does not throw the flag in that case. Or offensive holding against a defensive player on the opposite side of the field who could not possibly have made the tackle.
In the case of Georgia's #45 and Najee Harris, the DPI was so obvious and Najee was the intended receiver and could easily have caught the ball, so the DPI flag should have been thrown, even though Ridley ended up catching the ball.
