WHERE HE STANDS: Carl Edwards climbed one position, from fifth to fourth, in the Chase standings after New Hampshire. He trails series leader Matt Kenseth by 36 points, is 18 points behind third-ranked Jimmie Johnson and leads fifth-ranked and Roush Fenway Racing teammate Greg Biffle by two points.

DOVER RECORD: 18 career starts, 1 wins, 8 top-fives, 12 top-10s, 0 poles. Best career finish: First in fall 2007. Was fifth in this race last year and 14th in this year's spring race there.

LOOKING AHEAD: Edwards has had a good start to the Chase and remains within striking distance of the three drivers ranked ahead of him. However, he needs to start closing the gap, especially on points leader Matt Kenseth, as the remaining eight races of the Chase unfold. Here's his thoughts on Sunday's race: "We've had a pretty solid start to our Chase and we are hoping for great things at Dover. We've had a lot of success there as a team. Our group has worked very hard and we feel like both Greg and I made a pretty big breakthrough last week at New Hampshire with the way we ran there. This is grueling track, it's a tough place, it's very fast, it's hard on equipment, it's hard on the driver and hopefully we can run as well as we have historically here. We'd love to get in victory lane and close that gap on Matt Kenseth and those guys in the top three positions; they've done a great job so far. Eight races to go, a lot of racing left."

LOOKING BACK: Edwards tried to keep pace with Matt Kenseth and Kyle Busch at New Hampshire, but just didn't have quite the car to do so, ultimately finishing ninth.

ETC.: Edwards has completed 98.8 percent (7,117) of 7,204 total laps contested in 18 career starts at Dover. His average start is 15.2 and average finish is an outstanding 8.6. He has zero DNFs there.

16 GREG BIFFLE, Ford

Team: Roush Fenway Racing

WHERE HE STANDS: Greg Biffle had the biggest jump upward in the standings of any driver after New Hampshire, climbing from 11th to fifth. He trails points leader Matt Kenseth by 38 points, is two points behind fourth-ranked and Roush Fenway Racing teammate Carl Edwards, and leads sixth-ranked Kevin Harvick by one point.

DOVER RECORD: 22 career starts, 2 wins, 6 top-fives, 10 top-10s, 1 poles. Best career finish: First in spring 2005 and fall 2008. Was 16th in this race last year and 15th in this year's spring race there.

LOOKING AHEAD: Biffle made it very clear at New Hampshire that he intends to be a major player in how the Chase plays out. Here's his thoughts coming into Dover: "Dover is a track the Roush Fenway cars have run well at and a place I've had some success at. As a driver, you have to be on your toes at Dover. We're running a lot better on these short tracks and coming off a third-place finish last week, I think we are going to be really good at Dover this weekend."

LOOKING BACK: Although he didn't lead any laps, Biffle had one of his strongest runs of the season at New Hampshire, finishing third.

ETC.: Biffle has completed 99.3 percent (8,745) of 8,804 total laps contested in 22 career starts at Dover. His average start is a strong 12.0 and average finish is an also strong 12.5. He has one DNF there.

29 KEVIN HARVICK, Chevrolet

Team: Richard Childress Racing

WHERE HE STANDS: Kevin Harvick dropped two spots in the standings after New Hampshire, going from fourth to sixth. He trails points leader Matt Kenseth by 39 points (after being just 15 points back heading into New Hampshire), is one point behind fifth-ranked Greg Biffle and leads seventh-ranked Kurt Busch by just one point.

DOVER RECORD: 25 career starts, 0 wins, 3 top-fives, 11 top-10s, 0 poles. Best career finish: Second in spring 2012. Was 13th in this race last year and eighth in this year's spring race there.

LOOKING AHEAD: Although he has a runner-up, third- and fourth-place finish there, Harvick has never won at Dover in his Sprint Cup career. He's looking to change that Sunday. Here's his thoughts on Dover: "I don't remember much of what happened during the race at Dover back in June. I'm a one week at a time, keep it current kind of guy. I don't like to think back on the past. But Dover is always a fun track to go to. You can be very aggressive in your driving style there compared to most other places. We'll go there this weekend and run as hard as we can just like we do every other weekend."

LOOKING BACK: After finishing third in the Chase opener at Chicagoland, Harvick struggled to a 20th-place finish at New Hampshire.

ETC.: Harvick has completed 98.6 percent (9,861) of the 10,004 total laps contested in 25 career starts at Dover. His average start is 19.7 and average finish is 15.6. He has one DNF there.

78 KURT BUSCH, Chevrolet

Team: Furniture Row Racing

WHERE HE STANDS: After climbing from a six-way tie for eighth into fifth after the Chase opener at Chicagoland, Kurt Busch dropped back two spots to seventh after New Hampshire.

LOOKING AHEAD: Busch has had some rough sledding at Dover over the last few races. He's looking for a bounce back this Sunday, particularly not wanting to fall further back in the standings. Here's his thoughts on Dover: "We know what we have to do there. It's a matter of execution and making the right strategy decisions as the race unfolds. We're coming off a so-so race at New Hampshire and feel we need to pick up the pace and show more muscle. There's still a long ways to go in this Chase. Avoiding trouble and mechanical issues in the next eight races are vital if you want to be a contender."

LOOKING BACK: Busch fought an ill-handling car much of the race at New Hampshire, ultimately finishing 13th.
