CONCORD, N.C. — Kyle Busch and Denny Hamlin have all but conceded the Nextel Cup title, while Jeff Burton and Martin Truex Jr. are pretty close to waving white flags.

Only four races into this Chase for the championship and the realization is setting in: If Jeff Gordon and Jimmie Johnson don't struggle in Saturday night's race at Lowe's Motor Speedway, nobody else has a shot at the Nextel Cup title.

"I know it probably won't happen, but it would be nice if Jimmie and Jeff quit sharing notes, started to hate each other and wrecked each other on the racetrack. It would really help the rest of us out," said Carl Edwards, sixth in the standings — 205 points out.

"I have a feeling they're going to keep plugging away and they're going to be tough to beat no matter what."

It's fitting that Gordon, the four-time series champion, and Johnson, the defending series champion, are at the top of the leaderboard. The Hendrick Motorsports teammates combined to win 10 races during the "regular season" and Gordon built a lead of more than 300 points in the standings.

But it was all jumbled back together when the Chase began last month, and everyone had high hopes for an intense 10-race push to the title. It was on course for it, too, as the top six drivers were separated by a mere 18 points after two events.

Then a bizarre race in Kansas jumbled the standings, and last week's 1-2 finish by Gordon and Johnson blew them right open. Gordon heads into Saturday night's event with a nine-point lead over Johnson, and Clint Bowyer sits in third, 63 points out.

Two-time series champion Tony Stewart is fourth, but fading at 154 points back, and everyone else is 200 or more out. The big deficit that anyone has overcome to win the championship is 156 points that Johnson rallied from last season.

The stark reality of it has forced several drivers to re-evaluate their goals. Instead of the title, they are now looking to salvage decent finishes.

"We don't feel the pressure of being part of the championship battle — at least not right now," said Hamlin, who is ninth — 262 points out.
