But if he [Webber] gets a good start to 2011, assuming he's still there next season, and is able to keep himself to no more than 10 points behind Vettel at any one point, or even ahead of Vettel, then what would RBR do? Back the man in front (Webber perhaps?) or concentrate on Vettel who could easily be 3rd/4th in the standings when it comes to crunch time?
RBR will always back their No.1 driver. This is a strategy which has been tried, tested and proven to work best. If you start backing your No.2 driver, over the No.1, your No.2 driver will sure enough, let you down. MSc/Bennetton/Ferrari used this strategy to crushing effect. McLaren/Hakkinen also won titles using the No.1/No.2 strategy.
The title result today confirms that RBR were 100% correct not to be back Webber. Had they asked Vettel in a previous race (Brazil I think), to let Webber win, Alonso would've been the champion today.
What we saw today was exactly the reason why Webber is No.2 and Vettel is No.1. In a good car, Vettel is able to mix it with the best. Webber, even with a car advantage, is unable to mix it with other top drivers.
If Vettel is 100 points behind Webber, mid way through next season, RBR will still back Vettel as he is perfectly capable of negating that deficit by the end of the season.
I think people on this forum don't realise the difference between No.1 and No.2 drivers.
No.1 drivers are expected to lead the team. They are expected to extract the maximum out of their cars during qualifying and in the race. All the pressure is placed squarely on their shoulders.
No.2 drivers are expected to assist the team in winning in the Constructors Title and to back up their team-leader, when required. In races, if the No.1 drops out, the No.2 driver is expected to take up the slack. No.2 drivers are expected to be steady eddies, who don't take risks, who always bring their car to the finish and who dutifully follow team orders.
At no stage is the No.2 "expected" to win a team the WDC title. If the No.1 driver fails to win the title in a competitive car, this will count against him. If the No.2 fails to win the title in a competitive, it will not count against him. This is why we see Massa still employed, despite being obliterated by Alonso. Had Alonso finished up 100 points behind Massa, he probably would've been sacked.
The best No.2 driver in the business (by far), is without a doubt, Jenson Button. Its been a long time since I've seen a No.2 of his ability. The guy is rock steady and makes zero mistakes, all the while staying a few car lengths behind his team-leader. Barrichello, Ricardo Patrese and Gerhard Berger were also great as No.2 drivers.
For all the extra responsibility and pressure, the No.1 driver is usually paid a significantly higher salary than the No.2 driver.
