Mick stood out to me as the most consistent driver, best starter, and also at least among the best in terms of racecraft. He leads the championship, secured an F1 seat, and I don't think that's undeserved, at all.
The starts are a great strength at this point in time, no doubt. Consistency, sure if you look at the results, but watching the races I tend to believe it was often more luck than anything. He could have ended up like Illot today in a number of races without really doing anything different. And racecraft... nah, I don't really see it.
But whatever, if he wins it, it won't be undeserved. It's always about being the best in the field around you, and I can't see any of the others this season deserving it any more than Mick, over the whole season.
