Mick in a simulator, a good amount of professional coaching, finding flaws and how to deal with them, some F1 engineers looking at data and finding the best setup, definately will do miracles if the rest is 'just amateuring around'. that sounds a bit harsh, but let's keep it like that.
additionally, nobody knows whether there might have been a minor positive development for Michael. Mental state is the most important, and the state of his father's medical condition surely will cloud him, perhaps not a huge thundercloud, but even a tiny fog will have an impact. who knows something happened, OR he has had some psychological help to 'really' deal with it, and he's now wearing fog goggles or stepped past the fog and can be the talent he really is.
that is not saying that he is even remotely close to Michael - he probably is talented, but just how much is a totally different question. Ralf was talented too, just not as much as Michael. Bruno Senna also had definate talent, just not anything like the great legend Ayrton. Whether his talent is enough to be a force in F1 is another story alltogether. He's up to a huge mountain. Even if he'd be as talented, i wonder whether it's a climb he similarly wants to make or even able to.
He might 'just' be happy enough by having a win. Perhaps a WDC under his belt. But whether he wants to reach his father's figures?
