For those who wanted Hamilton to win the 2016 championship, there are two races that will stand out.
Barcelona, where Rosberg took both himself and Hamilton off the circuit, and Malaysia where Hamilton experienced engine failure while leading and Rosberg gained 15 points.
If either of those events had not happened, it might have been a very different story.
Hamilton experienced engine problems or failures in 6 races this season. Rosberg had one race where technical problems affected his performance.
Hamilton won more GPs this season than Rosberg. Where Hamilton finished outside the top 3 in any race, it can be attributed to engine problems of one sort or another.
Mercedes (as a team) got their act together and sorted reliability issues towards the end of the season. By that time, it was almost a maths problem - so long as Rosberg was no worse than one place behind Hamilton at the end of any race, he would win the championship.
Of the two, I think Hamilton has been the better racer. But maybe, like Colin McRae, he's just too hard on the car? Maybe Rosberg has more mechanical sympathy, ultimately making him the better driver (this year)?
Suggesting Hamilton would take Rosberg out in Abu Dhabi is silly. That would most likely result in neither finishing the race, and Rosberg would have been champion anyway.
Hamilton played the hand he was dealt the best way he could. Had Rosberg been driving a Ferrari in second place, the Mercedes team would have been telling Hamilton to slow down in the hope that Rosberg would have been passed in the closing stages.
It could be interpreted that the team orders (would have) favoured Rosberg on this occasion, while Hamilton still had an opportunity for a win. Whether that was deliberate or not is speculation.
