Wasn't Frank Dernie Williams' consultant engineer in the time Rosberg started his career there in 2006? I gues his personal sentiments have nothing to do here?
Don't get me wrong I think Robert and Nico were even matched this season. Allen: I’ve checked the data with various engineers and the Mercedes was faster on the whole /comparing to Renault/. Should we trust Allen or maybe he's Mark Hughes' brother-in-law?
I would still rate Kubica overall above Rosberg, no question about it - but not in 2010. Rosberg had a fine fine year. Well, maybe he was flattered by the fact how he won the intra team battle against an all-time great like Schumacher.
In fact, both Rosberg and Kubica extremely good and definitely in the Top Five, with Webber and Button completing the Top Seven (objectively seen, my personal opinion is a bit different as stated above). This is also reflected in the standings of this poll, which has Kubica/Rosberg/Vettel/Alonso/Rosberg/Webber/Button ahead, all in all quite fair and true to what we have seen this year. Also Kobayashi in close 8th position is fairly representative.
Frank Dernie may be close to Rosberg, but that does not take away from the fact that he is not so wrong in stating how good Rosberg was in 2010. In my eyes he was, besides Kobayashi, the revelation of 2010.
Relative to Kubica it would be interesting to see, we have no direct comparisons. How good is the Renault, how good the Mercedes? How bad is Schumacher, how bad is Petrov? I would still assume Schumacher is much better than Petrov, thus, the Mercedes may not have been that much better than the Renault at all, if these two cars were not indeed evenly matched at all.
To have Rosberg in 2nd goes a little bit far, I agree (I would put him in fourth before Kubica, only behind Alonso/Vettel/Hamilton), and I was also surprised to see Webber up in 3rd in Dernie's rating, ahead of Alonso and Hamilton...
