There are half a dozen drivers in the F1 field who are capable of leading the World Championship given a car as good as the Mercedes has been in the last four Seasons.
F1 is and always has been about luck as much as it is about ability. Alonso would likely have several more World Championship wins if he had gone to Mercedes instead of Ferrari and McLaren when they were both in the doldrums.
Stirling Moss is an example of a driver who should have been a World Champion.
How often have we seen great drivers have a run of bad luck that allows an equally talented competitor to beat them in the Championship.
