Not since Jamie Whincup's run of four-straight championships ended in 2014 has a Supercars driver mounted a successful title defence.
This year, that's Scott McLaughlin's task, as the Shell V-Power Racing driver goes from the hunter to the hunted.
It is, in effect, the fourth different role he has played in Supercars in as many years.
From GRM-Volvo giantkiller in 2016, McLaughlin became a DJR Team Penske recruit and title hopeful and following that near miss a driver out for redemption in '18.
McLaughlin now has that championship, sealed in the Newcastle finale in November, a fitting reward for a fine season.
It means the monkey is off his back, and the 25-year-old gets to reset to try to do it all again in 2019.
Such is the competitive nature of Supercars, though, championship defences have not been easy in recent years.
How the last five champions have fared
2013 champion Jamie Whincup
In 2014: Whincup made it four-straight titles, winning 14 races and finishing 583 points clear of runner-up Shane van Gisbergen.
2014 champion Jamie Whincup
In 2015: Whincup's title bid never really fired, five of his eight race wins coming after the enduros on his way to fifth in the standings.
2015 champion Mark Winterbottom
In 2016: After what's now Tickford dominated 2015, it fell hard, Winterbottom taking its only two wins and sixth overall.
2016 champion Shane van Gisbergen
In 2017: Van Gisbergen dominated the Adelaide opener, lost ground mid-year and stayed in contention but couldn't claw that back, finishing fourth.
2017 champion Jamie Whincup
In 2018: Whincup regrouped from an Adelaide DNF to lead the points briefly, but further niggling issues from there proved costly and he wound up third.
The new-car factor
If any of those bear any relevance to McLaughlin's situation in 2019, it is Whincup last year.
Most of his points were lost through the first half of the season, before Triple Eight really got on top of its new ZB Commodore.
Qualifying consistency with the incoming Holden was a thorn in the side of Whincup, van Gisbergen and Craig Lowndes until they were able to test in June.
McLaughlin's fortunes will likely come down to how much scrambling his team has to do with the championship's first two-door and its different aero package.
