NBC Sports' Nate Ryan joins USA TODAY Sports' Jeff Gluck in this week's episode that features an analysis of why Jimmie Johnson's win at Martinsville means much more than a run at title No. 7. Also, a look at the chances for Joe Gibbs Racing and defending champion Kyle Busch to make the Chase for the Sprint Cup final. The Toyotas looked strong as the Chase opened, but now the team is showing cracks. And what should fans make of the extended scoring snafu? Why NASCAR should have thrown a red flag.
