Jimmie Johnson's five-year dynasty in the Sprint Cup Series officially came to an end on Sunday at Phoenix International Raceway. After finishing 14th in the Kobalt Tools 500, his bid for a sixth straight series championship was over. Now mathematically eliminated, Johnson is 68 points behind heading into next Sunday's season-finale at Homestead, Florida. Kasey Kahne won over the weekend, but it's a two-horse race heading into the Chase finale. Just three points separate Carl Edwards and Tony Stewart. They are the only two drivers who remain in championship contention.
