Kevin Harvick and Denny Hamlin are still the two favorites to race for NASCAR’s championship this season and six other drivers are vying for a slot in the finale. The third round of the playoffs begin Sunday at Kansas Speedway and it is a crapshoot between the rest of the field. Brad Keselowski has four wins this season, the most of any driver other than Harvick and Hamlin. Chase Elliott has momentum following his win at Charlotte last week. But a win earns an automatic berth into the final four and the contenders will be seeking victory lane at Kansas.
