The NASCAR Sprint Cup Series leaves Texas Motor Speedway after an unusually quiet race.
There were only two cautions for debris. After the cautions, the cars ran a record 234 green-flag laps to finish out the race.
While Jimmie Johnson led a race-high 156 laps, he couldn't hold off a hard-charging Greg Biffle for the win.
This race showed how mistakes on pit road can be costly and how even top drivers can struggle just to keep up.
