How long before a fluke becomes a pattern, or a pattern becomes a trend? Not every driver is fortunate enough to drive the best car in Formula 1 for a single season, let alone two, but Nico Rosberg has been that fortunate - just not fortunate enough to convert that opportunity into a world championship victory.
For the second season in a row Rosberg finds himself vanquished by Mercedes team-mate Lewis Hamilton, this time far earlier and far more convincingly than in 2014.
Last year Rosberg could, rightly or wrongly, boil his loss down to chance. Everything rested on the double-points finale in Abu Dhabi. Rosberg qualified on pole position, but the car let him down. Hamilton won the championship. Simple.
