At Bristol, drivers have many X-factors to fear
This is a great weekend to be Tony Stewart, Jimmie Johnson, Greg Biffle, Rusty Wallace or Mark Martin. And not too bad a time to be Jeremy Mayfield or Kurt Busch, either.
They are the top seven drivers in the Nextel Cup standings heading into Saturday night's Sharpie 500 at Bristol Motor Speedway in Tennessee, and they have little to fear. Sure, Bristol is unforgiving, but each appears set to earn a spot in the Chase for the Nextel Cup unless the wheels completely fall off.
