I think it is an unproper time for Schumy to come back.
Rubens reported that MS doesn't save his tires, he uses to worn them out since the start and then try to hang on the whole race with it.
Without TC, I'm really doubt MS can do it without a massive change in driving style.
The first stint with full tanks will be very important in the race.
However, after seeing the Desafio das Estrelas kart challenge, all the Formula guys came ahead and MS seemed to have saved better his equipment to the end.
Du no...
But one think is for sure, several elements of the dream team are there:
> Ross Brawn Race Tactics
> Jean Todt running FIA
> Ruben development input [I don't mean MS depends on it, but it helps]
> The best engine
> The best [decent] chassis ???
> Ferrari and McLaren on a major revolution on their cars.
