I honestly think it is one of the areas of NFL game management that is still under appreciated by teams. There are well established principles most employ inside 4 minutes and inside 2 minutes. But basically in a game that isn't a blow out the whole 4th Quarter should be about playing the clock as much as the opponent and you just rarely see teams really start to think that way until much later. Being up two scores and snapping the ball with 20 seconds left. Or being down two scores and still regularly having the clock get inside 5 seconds. I am surprised analytics hasn't yet made teams smarter in those situations
