Dale Jr. running out of time for championship?

Dale Earnhardt, Jr. may be NASCAR's most popular driver, but he is deficient in driving talent

Dale Earnhardt Jr. is approaching a dangerous statistical marker as he enters his 10th season as a Sprint Cup driver. Only two Cup champions — Bobby Allison in 1983 and Dale Jarrett in 1999 — raced as long as Earnhardt has before they won their first title. It took Allison 18 years racing full time before he won his only championship, two weeks before turning 46. Jarrett did it in his 13th season, five days before he turned 44. Earnhardt is only 34, so time is on his side, but history isn't. Of all the drivers who have suited up as full-time competitors for 10 years or more, Allison and Jarrett are the only ones who became champions in their second decade of racing. ESPN
