Thoughts as NASCAR leaves Phoenix and heads to Homestead for the 2019 season finale:

— It’s imperative that NASCAR does something with the Cup aero package for shorter tracks before the 2020 season, at least in regard to shorter tracks. They simply can’t have the title race decided by 10 seconds. This was one of the worst races of the season, and we can’t have a repeat of that in 2020 when a championship is being decided at Phoenix. 

— There’s a lot of talk about young guns in NASCAR, and there is definitely lots of young talent in the ranks in all three major series. But look at the top ranks in Cup, and what do we see?: An average age of 38.5 among the final four at Homestead. The lesson: For now, experience rules. Chase Elliott, Ryan Blaney, Kyle Larson, Alex Bowman, William Byron and others will get their shot at the title soon enough. But they’re going to have to get past the veterans to do so, as long as they’re around.
