Well, I've got a couple of thoughts I'll throw out. Hamo will prove himself; he is, afterall, the youngest ever WDC. And the team made some critical mistakes as well. So I think the fact that he did not dominate is more about parity of the equipment, overall teams and drivers as well, rather than any failing by Hamo. (We don't have any real wankers in the field; the guys in the back are pretty good, just in poor cars) And nevermind the stewards playing more of a part than ever. One of these guys, Fred, Flippy and Hamo may emerge as a dominant Schumi type force as they mature if they get (or maintain) a dominant team organization and car year after year.
Giving Schumi his due, I personally think that the dominance of the Schumi years was due, in part, to what he did out of the car as well as in the car. If he's the template, a dominant driver is a team builder. Flippy does not appear to have the natural tools or background, but he is an excellent Schumi prodigy, so that could overcome his shortcomings. Hamo appears to have the cool and demeanor to be a leader, but we'll see; that's the one thing I think he needs to prove. Now Fred, maybe he'll be a benevolent dictator in the right team, but he's not always as smooth out of the car as he'll need to be. I would think he's the guy with with the toughest row to hoe to go down in history as dominant.
Just my 2 cents.
