DETROIT — Dale Earnhardt Jr. said Thursday he's proud of his accomplishments after Kevin Harvick suggested NASCAR's growth has been hindered because Earnhardt hasn't won enough. "I put a lot into this sport, and I know that I might not have met everyone's expectations, but I certainly exceeded my own," Earnhardt said while appearing at Chevrolet's event introducing the Camaro ZL1, a new race car for next year's NASCAR Cup Series. "I'm super proud of what I've been able to accomplish, and I hope that I brought something to the table and left a good impact," Earnhardt added.
