Keep in mind that each year brings new surprises, new top teams and new struggling teams. Think of the Braun team a few years ago. Or just look at how dominant Red Bull was last year compared to this year, where they were often no better than other teams.
Hamilton could get lucky and be with a top team - or not. That's why they actually run 20 races, instead of just doing it all on a simulator.
Any word on Robert Kubica?
