#2 Jimmie Johnson
Keep in mind that this entry is contingent on Jimmie Johnson breaking the record for most Cup Series championships by a driver, but with 16 years, 83 Cup Series wins, two Daytona 500’s and one of the most dominant runs NASCAR history, it would make sense for Johnson to finally hang it up. In fact, if Johnson were to capture his 8th Cup Series title in 2018. one would have to wonder what he would have left to prove?
With that being said, Johnson has already admitted that he would happily retire from the sport after winning his eighth championship and while he will have to be the first repeat champion under the new system to do that, Johnson has built his career on firsts. Whether he can add one more firsts to his historic career remains to be seen and will be interesting to watch it all play out in 2018.
