I respect Rosberg's decision, though I'm very much surprised by it. I would have preferred he stayed for at least one more year at Mercedes, because now I think there'll always be question marks over whether he could actually beat the rest of the field in a fair fight. He had easily the best car, and his only real rival had more mechanical issues over the course of his championship season. Now I'm not saying that Lewis would have been champion if not for Malaysia, but there's a lingering doubt in my mind as to whether Rosberg deserved to win. I had the same thoughts about Vettel when he was at Red Bull.
It's been a bad year for the sport; another dominant Mercedes, other former champions pootling around in lacklustre cars, a Red Bull that's still not quite good enough to win regularly, It's not all been gloom, at least we've seen the rise of Verstappen and a bit of a comeback for Raikkonen, but it seems to have been a year consisting largely of moaning about one thing or another. Remember that dreadful qualifying system we started the year with? Vettel's constant moaning about other drivers and blue flags. Everyone moaning about Verstappen's aggression, justified or not. But the thing that's bothered me the most is the absolutely incessant coverage of Rosberg and Hamilton's relationship and "what's really going on at Mercedes". We've probably skipped half of the buildup shows this year, just because the coverage was practically identical for every race, at least on Sky.
I'm hoping the new rules balance the field a little more for 2017. We need some unpredictability back in the sport. I don't want to see Mercedes replace Rosberg with someone substantially worse than Hamilton and end up with a dead cert for the championship if the Merc is the class of the field again. I think the fact that there's been half as much discussion here this year as there was last is telling as to people's waning interest.
