The Chase for the Sprint Cup Championship kicks off this weekend with the GEICO 400 at Chicagoland Speedway, and racing fans are excited for what many agree is one of the best fields in years.

NASCAR runs many races throughout the year, but the field is narrowed at a certain point down to 12 drivers, based on the points standings from the previous races. These drivers then have their point totals reset and compete in the 10-race "Chase for the Sprint Cup." Essentially, this format mirrors the postseason playoffs of other major American sports.

Of course, sometimes the most popular drivers don't qualify for the final 10 races. Yet NASCAR executives are excited this year, because many of the top racers have earned spots in the Chase.

"We couldn't have written a better script," Chicagoland Speedway president Scott Paddock told the Chicago Sun-Times. "Jeff Gordon is in the Chase, Dale Earnhardt Jr. is back in it after three years absent. The Busch brothers (Kurt and Kyle) are running well. Carl Edwards, Ryan Newman, Tony Stewart ... it couldn’t be any better. Plus, it is supposed to be cool this weekend, which should produce fast times."

No doubt NASCAR fans will be focused on Chicago this weekend as they watch these racers battle it out for a chance at the coveted Sprint Cup.
