CHARLOTTE, N.C. -

If there's one Sprint Cup driver more anxious than any other to return to the track, it has to be Brad Keselowski -- the 2012 Sprint Cup Champion.

But he and the No. two team struggled all season long last year, limping to a 14th-place points finish and posting just a single win. And that didn't come until the 31st race of the season at Charlotte last fall.

Keselowski is out to bounce back this season while proving that his championship was no fluke.

“I think there were quite a few areas where we know we didn't hit it and we know we can hit it better. We've made adjustments behind closed doors,” Keselowski said. “And because I don't want our competition to know what they are, I won't dig into them too deeply but we already mentioned some of them with our pit crews and making pretty massive adjustments to those. I don't feel like we were that far off from before so I think we are in a very strong position headed into 2014.”
