In general terms a conundrum is defined as a difficult and confusing problem. In Nico Rosberg terms the conundrum is Lewis Hamilton. The latest win in Texas gives Hamilton five consecutive race victories and leaves Rosberg without any answers.

As the weekend started to take shape it was Rosberg who stepped up to the qualifying plate. The German got the better of Hamilton by a hefty four tenths which Hamilton would later chalk up to “brake issues.” Nevertheless, at the first hurdle it was Nico Rosberg who pulled it off.

The first stint of the race too was all Rosberg as he controlled the initial laps. The sting was taken out of the start of the grand prix as a collision between Force India’s Sergio Perez and Sauber’s Adrian Sutil brought out the safety car on lap one. Both drivers’ race was ended by the coming together and Perez has been given a seven place grid penalty for the Brazilian GP.

The two Williams drivers, very much embroiled in a constructor’s fight with Ferrari, shadowed the Mercedes duo for the first stint of the race without ever being able to launch a serious threat on any of the first two positions. For the most part Felipe Massa looked set for the final step of the podium but Red Bull’s plucky Aussie once again lived up to his billing. Daniel Ricciardo snatched third from the Brazilian in yet another afternoon of mighty fine wheel-to-wheel racing.

By lap 24 Hamilton has eroded the two-and-a-half second gap that Rosberg had steadily built and flung his car down the inside of Turn 12 and into the lead of the race. It wasn’t a swashbuckling, throw caution to the wind kind of move either from Hamilton. It was calculated and infused with an ominous hunger. Five straight race wins sends quite an imposing message to the other side of the garage.

For once Valterri Bottas finished second to teammate Massa in a quiet fifth place. Fernando Alonso dragged a reluctant Ferrari up to sixth and managed to hold off a late charge from Sebastian Vettel. The Red Bull driver’s didn’t look sharp after a pitlane start but a late stop for fresh rubber breathed some life into his afternoon. Kevin Magnussen brought his McLaren home in eighth ahead of Lotus’ Pastor Maldonado. The Lotus turned out to be the surprise package of the weekend and ran competitively in the points for most of the afternoon.

Jean-Eric Vergne was stripped of ninth place after incurring a penalty for a collision with Romain Grosjean. The Frenchman ultimately finished tenth. The mid-field battle for points was responsible for some spicy wheel-to-wheel battles as several drivers duked it out. Both Jenson Button and Kimi Raikkonen finished outside the points and a lap down on the leaders.

Besides the mega quick Lewis Hamilton-shaped conundrum that Nico Rosberg has he faces an even bigger dilemma. Rosberg’s problem isn’t that he can’t win it; it’s that he doesn’t know how to win it. He hasn’t had to deal with an unrelenting teammate before certainly not while at the same time being the focus of so much attention. Hamilton’s move to take the lead of the race came from pretty far back and it was Rosberg’s caution that consigned him to second best. This isn’t a call to throw all rationality out of the window but through all of this sport’s history it has been courage that has made and defined its champions. As impressive and consistent as Rosberg has been this season he just doesn’t seem to have the uncontained hunger to win it.

It is far from over and Brazil’s legendary Autodromo Carlos Pace has always been the wildcard in the Formula 1 calendar. Here, the unpredictability seems to ratchet up a notch or two and it tends delivers some of the most astounding results. Rosberg faces a deficit of twenty-four points and call to unleash all he has on a near unbeatable teammate.
