NASCAR has been filled with edge-of-your seat races, daring drivers who constantly push the limit and thrilling championship runs.
It’s also been filled with several title defenses that didn’t work out the way drivers had hoped for.
Not every champion was able to come back the following year and successfully defend his title. In fact, it was a rare occurrence for someone to win back-to-back titles.
Not everyone had a bad title defense, though. Some drivers came back and barely missed winning for a second straight year. They battled hard but came up just short of successfully defending their title.
Other champions, though, struggled throughout the season or ran into other problems that prevented them from being a factor in their own title defenses.
Not everyone can come back and run as well as they have the previous year; we’re seeing it firsthand this season with Brad Keselowski, and these 10 drivers had the worst title defenses in NASCAR history.
