I don't think you could make a judgment on his driving based on time lost on the opening super special. There are plenty of good reasons to go cautiously on that stage.
Atkinson lost 7.3 seconds on that stage, because he stalled the car.
I think Wilson's advantage is that he's on the world stage at such a young age. I mean, virtually his first rally car was a 2nd-hand Focus WRC. The downside of this is that he has had to do almost all of his learning in the full scrutiny of the WRC, whereas most other drivers have at least had a few years of learning the trade in local or national championships before stepping up.
So much of rallying relies on experience, and you can only get that experience by getting out there.
Having said all that, I think that this year Wilson has to step up and show that he belongs in the WRC. He needs to match times, at least, with Galli to be taken seriously.
