Just three races remain in NASCAR’s Sprint Cup Series, and Jimmy Johnson has all but wrapped up his fourth straight title. He would be the first driver to achieve this feat in the 61-year history of the championship. Of course, NASCAR has had its dominating drivers in the past: Hall of Famers Dale Earnhardt and Richard Petty became racing legends as they each racked up seven Cup titles over the course of their careers. Jeff Gordon seemed to be on pace to match their record when he won four titles in seven seasons from 1995-2001. Cale Yarborough won three straight championships from 1976-1978. However, for Johnson to be on the verge of winning four in a row under today’s racing rules is difficult to fathom. This is a sport which goes to great lengths to guarantee equality of equipment, and which has beefed up its compliance policies and punishments to ensure a fair playing field (or chassis). NASCAR also revamped the championship point system in 2004.
