NASCAR: Championship 4 locked in

The credentials of the Championship 4 are nothing to sneeze at.

• Joey Logano, who led the series in wins, poles, top-10 finishes and average start in 2015, is seeking his first championship.
• Carl Edwards is a two-time championship runner-up.
• Kyle Busch, the defending Sprint Cup champion, is the second driver under this format to reach the final four in back-to-back seasons.
• Jimmie Johnson is looking to join Richard Petty and Dale Earnhardt as the sport's seven-time champions. His five consecutive championships are a record. 

The Sprint Cup championship finale at Hometead is next Sunday at 2:30 p.m. ET.
