Pro Could bring back older fans.
Believe it or not, NASCAR implementing the new playoff format in 2014 was the final straw for several longtime fans of the sport and destroying the system completely could bring some of them back. Of course not everyone is going to come running back to a sport that has made ridiculous decison after ridiculous decision, but it would at least be a step in the right direction.
In the end, NASCAR fans, especially the older ones, want to be heard and what better way to hear them out then to bring back the old format that everyone loved. Sure, the move would have its drawbacks, but NASCAR might be wise to chase after the fans that were actually dedicated to the sport, instead of fans who might or might not have any interest in the sport at all.
