They've never really gotten their package to work well at Malaysia.
Plus Kimi had his engine revs turned down to make sure they got important points.
Both excuses, but I honestly believe that if Kimi or Massa had gotten in front of Hamilton, it would have been a different race. Ferrari was running too much downforce. Perhaps hedging their bets on a tropical wave, as has happened many times at that venue.
Either way, great win by McLaren. I expect Sahkir will be different this weekend. For starters I expect Renault to insert themselves into the podium battle.
