First up is this Sunday's marathon known as the Coca-Cola 600. Seven times the driver who won the Sprint All-Star race went on to win NASCAR's longest test of man and machine. Jimmie Johnson (22.2) certainly has the potential to up that number to eight, but teammate Kasey Kahne (21.3) is my favorite.

Joe Gibbs Racing teammate Kyle Busch (21.2) looked very strong in the All-Star event and has a shot to win at Charlotte again, as does Clint Bowyer (21.5), who grabbed the checkered flag last fall.
