No. 4 Jeff Burton

Jeff Burton won the most recent NASCAR Sprint Cup Series race, two weeks ago at Bristol Motor Speedway. He was part of a Richard Childress Racing 1-2-3 sweep.
He is also a past winner at Martinsville Speedway in Virginia, site of Sunday's Cup race. But that win came in 1997. His past five races at Martinsville have produced only one top 10, that was a sixth place in last year's spring race at the track.
Still, Richard Childress Racing appears to be the strongest team in the Sprint Cup Series after the first five races of the year. It has all three of its drivers in the top 10 in the Cup standings, faring much better than rival Hendrick Motorsports, with its all-star driver lineup of Jimmie Johnson, Jeff Gordon, Dale Earnhardt Jr. and Casey Mears.
But Burton said after winning the Bristol race it's too early to say that Richard Childress Racing has surpassed Hendrick.
"We'll talk about that in December, you know," said Burton, driver of the No. 31 Chevrolet for Richard Childress Racing. "I can assure you that the 24 (Gordon) didn't run the way that you normally see them run here. You wake the sleeping giant, they're going to be hard to beat. There's no getting around that.
We can answer that question in late November. We can't answer it today."
Childress, who also owns the Cup teams for Kevin Harvick and Clint Bowyer, echoed Burton's thoughts on Hendrick.
"You know, I think they're a top caliber team, top caliber drivers," Childress said. "But, you know, they were strong last year, and everybody shoots at who is the best. Last year they were the best, and we had to put our sights on them."
