At the end of Sunday's Quicken Loans Race for Heroes 500 at Phoenix International Raceway the championship picture will be crystal clear. Three drivers will join Martinsville winner Jeff Gordon in the Championship 4, while four other Chase drivers will have their title hopes crushed.

Many believe Kevin Harvick is the man to beat Sunday at Phoenix, as the defending series champion attempts to make history by winning his fifth-straight race at the 1-mile track.

However, his Stewart-Haas Racing teammate Kurt Busch and last week's winner Jimmie Johnson have shown throughout the weekend that Harvick will not simply walk away with the win Sunday afternoon.

Few know what to expect Sunday afternoon, but it should be fun to watch unfold.
