AVONDALE, Ariz. -- During his peak years at Richard Childress Racing, so many of Dale Earnhardt's championship runs were fueled by reliability. During his 1990 title quest, he finished 28 of 29 points events and during one 13-race stretch completed all but three laps. In 1993, the Intimidator finished 28 of 30 races, and clinched his sixth NASCAR crown by completing all but five laps in a 15-event span late in the year. His black No. 3 car was often as durable as a tank.

That legacy is evident today within the Childress organization, whose three cars lead the Sprint Cup tour in percentage of laps completed entering Saturday night's Subway Fresh Fit 500 at Phoenix International Speedway. That durability is a large reason why RCR drivers Jeff Burton, Kevin Harvick and Clint Bowyer stand first, second and 11th, respectively, in the series standings, without a single DNF -- the NASCAR abbreviation for did not finish -- between them.
