I was talking about Tanak. Nueville got lucky with Tanak's misfortunes and offs and big congratulations to him on his first title. But imo neither would have won had Rovanpera been full time. Possibly Ogier as well.
You play the cards that you get, I know that not a single season is the same, but looking at the WRC history, I don't think that this title should be viewed as some sort of "If XYZ he wouldn't have won". After all, these are not?
1983: Hannu Mikkola becoming the first and only driver (at that point) to do all rallies in a season, winning the title. Audi only car with 4WD
1984: Stig Blomqvist becoming the second driver in WRC history doing all rallies in a season, winning the title. Teammate Mikkola stuck with the old Audi the whole season while Blomqvist got the Sport Quattro.
1985: Timo Salonen doing several more events than anyone else. Vatanen getting seriously injured halfway through the year. Audi doing half the events. Lancia still using an RWD car at times. A Mazda RX7 on the podium on gravel!
1987: First Gr.A year. Lancia had a Gr.A car properly ready. Mazda had a 4WD car. Ford entered a 2WD in many events. Kenneth Eriksson ended the season 4th, in a FWD Golf. Two rallies won by 2WD Gr.A cars.
1988: Did anyone say Lancia-cup? Reigning champ Kankkunen had left for Toyota, who took until round 5 to even have a 4WD car ready. Often it was Lancia v Mazda.. Several 2WD podiums, even at Monte Carlo(!)
1989: Still just Lancia with a competitive Gr.A car, with the team picking what drivers to send to what rally. This was the year a 2WD Group N car won a WRC event.
1990: No dropped scores, Sainz doing all but one round, arguably only Sainz, Kankkunen, Auriol and Biasion were "big names". Auriol and Kankkunen skipped 3 rallies, Biasion skipped 5.
1993: Dropped scores, Kankkunen and Auriol doing more rounds than any other works driver, thus Kankkunen being the only one who ended up dropping a score. Jolly Club ran privateer Lancias.
1994: Auriol and Kankkunen being the only drivers doing every rally, Auriols only title.
1995: Sainz got injured - all he had to do in the rally he had to drop out of was to get a top 6. Only three times in the whole of 1995 did any of the near full-time manufacturer drivers finish outside the top 6 that year. Schwarz in Sweden and Mäkinen&Kankkunen in Corsica.
1997: It was a Mäkinen, McRae, Sainz battle, so the drivers were good. They were also the only full.-time drivers...
2001: Burns won one rally. What if Mitsubishi were allowed to use the Gr.A car the whole year? McRae not McRae'ing? Or Peugeot not imploding on itself for 60% of the season? I mean. Gilles Panizzi only won 1 asphalt-rally that year, only scored in 3 rounds and got half the points Burns got!
2008: Ford used the 2007 car for over half the season, their top driver were Hirvonen. That's the challengers Loeb had that year.
2009: 4 works seats. Ford again delaying the new car.
2010: See above - I mean, Petter Solberg ended up 2 points behind Latvala in 2nd in his private C4.
Then you have some extremely dominant VW years...
Yet, I rarely see anyone mentioning anything about those.
I guess this shows how rallying is difficult when you're not committed full time.
Even Loeb started to make more mistakes once he stopped full time.
I guess it is due to motivation. Rovanperä was seemingly very tired of travelling around. Ogier didn't look happy at all when he won in Finland and said he guessed he "had to do the rest of the rallies". It wasn't a "I will do it to try to win" it was a "I guess I have no other choice due to the championship standings... -.-"
