Everyone assumes that Vettel will have other chances at the WDC.
But is that true?
Kubica has been pegged as a future champion. Kobayashi, Rosberg, Hulkenberg have all shown promise. Even Petrov's game has grown over the season.
Alonso, Hamilton and Button have a few years left, and though Webber's career seems to be winding down, he could still be competitive for years.
There's no guarantee that RBR can be as good next year, or the year after... will Vettel have the same drive as RBR gets back to the top?
Or look at Massa... a horrible injury, and he's just not the same. Things like that no one can predict: you can't sit back and wait in this sport!
I'm like everyone else, I think Vettel has the talent for greatness... and yet I wouldn't be shocked to see him turn out anything but an also ran if he doesn't win this year.
