Con: Kills consistency
NASCAR has a huge consistency problem and a lot of that has to do with the fact that they have been implementing new format changes for the last three years now. Not only does that make NASCAR look like a complete joke of a sport, especially if they ultimately decide to scrap their shiny new playoff system in favor of the non format that almost killed the sport, it also hurts the legitimacy of NASCAR as well.
NASCAR need to make a decison and still with this time. No more gimmicks, no more additions and no more artificial excitement to bring fans in. They either need to take the format as it is, which would be a positive step for the sport, or go back to the old way of doing it and bring back the old fan base that used to love the sport unconditionally.
