Driving style and new package

I was a reading an interview with David Coulthard and the question about how drivers would have to adapt to the new aero package. He said that drivers won't be able to drift as much because of the slick tires, more grip at the rear.

Lewis Hamilton likes to have an over steery rear end, perhaps the new package doesn't suit his driving style? Maybe that is why the Macca isn't on the pace right now.
Now is his chance to prove he can develop a car, like Alonso does.
