Hendricks Motorsports driver Jimmie Johnson enters his car at Michigan International Speedway in Brooklyn, Mich. , Saturday, June 16, 2007. With a pair of superstar drivers in Johnson and Jeff Gordon and an unbelievable winning percentage this season, Hendrick Motorsports was already the best in NASCAR.
