My opinion on using field marking are use them when you can. After kicks, Long first down, etc. critical spots such as near the LTG or inside the 10, coming in or going out should be placed exact. If a new series does not start “on a tick”, in these situations, so be it. Basically use the field markings to make the game run smoother where you can, but some spots are critical and a foot can be a really big deal.
