Pro: More exciting
NASCAR has some kind of kink with making things exciting. Not only is that evident by the multiple points format changes , but also by the implementation of stage racing, caution clocks and a overtime line rule that made everyone want to pull their hair out. In fact, the decision to add a restrictor plate all star race falls right in line with what NASCAR has done in the past.
With that being said, it will be really interesting to see how this new format plays out and if it can actually bring that excitement factor that NASCAR has struggled to find for years. Will it live it up to the hype though? while its impossible to say that until we see the race unfold, its seems that they are heading in the right direction with this decision.
