Kyle Busch is finding it more challenging to describe his season after each win. He's gone from excited to humbled and now this.

"This is something that's crazy," he said earlier this month after his win at Chicagoland Speedway. "This doesn't come along very often."

Busch is having one of the best seasons in recent years in NASCAR, but if you look deeper one can appreciate even more the success he's had and there's still four months of racing to go.

.368

Kyle Busch's winning percentage -- seven wins in 19 starts. You have to go back to Jeff Gordon's 13-win season in 1998 to find a better win percentage by a Cup driver. With only 33 races in 1998 (this season has 36 scheduled races), Gordon's winning percentage was .393

MAGIC NUMBER

Kyle Busch is the 17th driver in series history to have at least seven wins in the first 19 Cup races of the season. Eleven drivers in that category went on to win championships -- the last was Jeff Gordon in 1997. Two others finished second in the points. None, though, come from the present era with the Chase for the Sprint Cup, which began in 2004.

FIVE ALIVE

Kyle and Kurt Busch (left) have won the past four races -- the first time brothers have won four Cup races in a row since the Flock brothers (Tim and Fonty) performed that trick in 1955. Brothers have never won five Cup races in a row, something the Busch brothers would accomplish with a win in today's Allstate 400 at the Brickyard in Indianapolis.

PACING THE FIELD

Kyle Busch has led 43.1 percent of the laps in the seven races he's won this year. His most dominant performance came at Infineon Raceway when he led 69.6 percent of the 112 laps on the road course.

NO BACKFLIPS

Four times Kyle Busch has won a Cup race, Carl Edwards (right) has finished second -- including three times this season. Busch has never finished second to Edwards. The driver who has been toughest for Busch is Jimmie Johnson. They've finished first and second four times with Johnson winning three of those occasions. Busch beat Johnson two weeks ago at Chicagoland Speedway when he passed Johnson for the lead with two laps to go.

DO I KNOW YOU?

The belief is that it often takes a year for a driver and crew chief to develop chemistry and have success. Not Kyle Busch. He had never worked with crew chief Steve Addington until joining the Joe Gibbs Racing team prior to this season. Busch is one of only two drivers in the top 12 in points with a new crew chief this season. The other is Matt Kenseth, whose crew chief used to his team's engineer.

A look at the most wins among NASCAR's top series in a season since the modern era (1972) and how Kyle Busch compares. Note: Must have at least one win in two different series to count.
