#2 More road course races.
If nothing else, The new roval playoff race proved that road course racing could be fun again and that it belonged as a stepping stone in the ten race playoff schedule. Interestingly enough however, it opens up the possibility of NASCAR doing this with other tracks to create a new experience for race fans.
Some NASCAR fans have even been floating the idea of tracks that get more than one Cup series race a year doing one of them one a roval course. Not only would that create more intense and action packed racing at tracks like Michigan, Pocono, Talladega, Daytona and California, it also fits in very well within a shorter season.
