No, we still have reporters and journalists who get their hands dirty. Local news is one thing, national sports is another.
The astonishing lack of knowledge and unwillingness to gain knowledge wouldn't be tolerated in any other sport. NFL writers are expected to know what's going on in College Football and even High School Football. MLB writers are expected to know what's going on with farm teams. Or, at least people within the organizations that cover those sports are expected to know.
NASCAR? Not just no but hell no. Instead of spending time researching what goes on in the lower leagues and gaining knowledge, they're busy talking about what Brad Keselowski tweeted or speculating what color socks Kasey Kahne wore yesterday. They won't go to the Snowball Derby because there isn't a cushy media center with free food and drinks. Hell, some of them bitched about going to Eldora because their shoes got dirty, or something.
And then, when there is a driver who comes up from short tracks in to NASCAR, they don't make even the slightest attempt to gain any knowledge. If it's not on Racing-Reference or Wikipedia, that driver doesn't exist. Unless they're racing for Hendrick, Roush or Gibbs.
