Greg Biffle finished a middling regular season as a driver who just couldn't win. Now, he's the one who simply can't lose. Biffle traded a lengthy winless streak for a winning one when it mattered most. He made it a sparkling 2-for-2 in the Chase for the championship Sunday, using another late pass, this time with nine laps to go, to hold off Matt Kenseth and Carl Edwards and bolster his bid for the Sprint Cup title. Up ahead for Biffle is a trip to Kansas City, a track where he won last season before starting a 33-race winless streak. That dismal skid seems as much behind him as his Roush Fenway Racing teammates Kenseth and Edwards were over the final, thrilling laps at Dover International Speedway.
