Many will say, as they did with Vettel and Schumacher before, that it was all car. Yes, but it's not really Hamilton's fault everyone else was slow. Nico was not slow and in the end Lewis beat him fair and square.
Given Mercedes' crushing domination it was always going to be between Hamilton and Rosberg for the win. In fact Rosberg proved to be a more tenacious competition than anyone would have imagined at the beginning of the season, he came close and surprised everyone by out qualifying Hamilton.
For Lewis, he did not have it all his way, he made a number of mistakes and fell short in qualifying but he always fought back on Sundays. He had bad luck but also good luck, sometimes in the same race. Hungary, for example, where an engine fire forced him to start from pit lane and a safety car helped him finish on the podium. Or Brazil, where he spun off while chasing Rosberg but managed to keep it away from any barriers and with the engine running.
If I had any recriminations, it would be with the way the (mostly) British media followed Hamilton's lead and demonized Rosberg for presumed dirty tricks. What was ridiculous in Monaco just became lousy after Spa. Mercedes as a team were wrong to come down hard as they did on Rosberg, even Toto Wolff in hindsight admitted as much to the BBC, ahead of the last race. It was a blotch in an otherwise very well managed, complicated season for the Germans. Was Hamilton wrong in whining about Nico's behavior, using his contract renewal and even his background in the media/psych war? It's F1, win at all cost, no holds barred, that's the way it is.
So well done Lewis, congratulations and get a nice rest, hopefully next season you will have more than just Nico chasing you. It will be much more fun for us to watch and for you to race!.
