Podcast: Dale Earnhardt Jr.'s concussion saga

NBC Sports' Nate Ryan joins Paste BN Sports' Mike Hembree in this week's NASCAR podcast. The focus is Dale Earnhardt Jr., the sport's most popular driver, and whether he will - or should - return to the race car after a sobering news conference in which his doctors stressed  their 'goal is to see him become a human being again.' The duo also lends clarity to the Chase for the Sprint Cup picture heading into Richmond and Martin Truex Jr.'s win in the Southern 500.
