I think its predominantly down to the fact that Mercedes altered the car setup to wet track settings, whereas everyone else didnt bother to change their car settings when the race was red flagged.
Dont forget that Rosberg overtook Hamilton after the SC went in and he was running 4th behind Alonso.
With the irony of that being, had Lewis stayed in 4th he'd likely have been taken out by Webber.
All in all, decent performance by many, Sutil was the class of the field, the most entertaining guy out there for sure
Overtook constantly and made so many mistakes, it was like playing an F1 game where you play the first race, take loads of places but make loads of mistakes as you learn the breaking points.
Button, laughably bad, I can't believe his car was really any worse than Hamiltons. Yes he was further back, but he had chances, they were saying the SC ruined his pit stop, to some degree yes, but then when the race restarted he was on better tires than all those around him, and he did NOTHING, at all. End of the day when the SC came in, lots of people ahead got free pit stops, those around him didn't, with fresh tires and a SIGNIFICANTLY better car and was MUCH closer to the front of the grid(ie within 10-15 seconds where as before the SC, he was miles and miles down), he actually had the chance with a better car and better tires and being that close to really push up the field, he did NOTHING, literally nothing.
Useless, lots of people had bad tires, Lewis said his inter's were wearing on the first lap behind a safety car, at the end everyones tires were a joke(well most peoples).
Hamilton's only, and biggest mistake was coming out of the SC, I think the McClaren just wasn't fast enough and Alonso would have gotten past anyway, but had he not screwed up that one corner he might have won the race.
The race was all about SC's, and really thats it. You have a couple mentalists do some funny overtaking and spinning, but most of the real runners were fairly boring.
The other problem was, no one really knew how much fuel was required, I'd guess some people took bigger risks assuming a long time on safety cars and filled up with less fuel.
Did Schumi/Nico really have a wet race setup, or was it mostly their first sector advantage showing.
Remember down the straights with an f-duct aswell a powerful engine has a huge advantage, while the massive cornering advantage was heavily effected by the rain. IE Schumi/Rossberg could go down the straights faster than anyone in the dry or wet, Red Bulls could normally destroy everyone in sectors 2/3 in the dry, in the rain their advantage was MUCh smaller.
Schumi still handled the car well, overtook very well, looked fast and aggressive.
