Jimmie Johnson extended his points lead as he won the race at Phoenix this afternoon. Johnson led 217 of 313 laps to stretch his lead to 141 points which means he has only to finish 36th or better at Homestead in Miami to capture his third straight title. Many people do not realize how tough that is too do. Winning three straight Nextel Cup Championships is really tough. if you do not believe that just go back to see how many teams who won a championship lost the following year.
