Oh, how times have changed.

The commotion over when defending Sprint Cup champion Jimmie Johnson would put a win on the board in 2014 has reverted back to a more familiar theme: Can anybody stop him?

Johnson picked up his second consecutive win yesterday at Dover International Speedway and is heading for Pocono Raceway, where he won last June.

So, again, can anybody stop him? Leigh Diffey and Wally Dallenbach of NASCAR AMERICA pondered that question today…

The two also focused on Brad Keselowski’s critical comments about his No. 2 Team Penske pit crew after finishing second.

Dallenbach explained a driver’s frustration over losing positions earned on the track during a stop, but also noted how important a pit crew’s contribution can be.

NASCAR AMERICA returns tomorrow at 5 p.m. ET on NBCSN and NBC Sports Live Extra. For more clips, check out the show’s archive page.
