I like Kubica a great deal. I genuinely believe he is hungry and dedicated enough to challenge for world championships but he needs a top seat to do that. But really, 2ms, that statement is quite a stretch. Not saying it's wrong, but nothing in what you have presented makes it right either, does it?
Hmm. That it's possible he could be 4th if was driving a Ferrari rather than Renault? I mean, he has 73 points (1 point out of 6th) to Alonso's 94. The Ferrari has generally been at least the second best car all season (though the McL now looks like may have now caught up or passed it) whereas the Renault is considered well back...
It was well back when Alonso was driving it too of course. No question about that. And in fact I do think that, based on the fact Alonso drove well in 05,06, and 07, there's evidence that he would be able to do better than the 9th he got last year if was driving this year's Renault (i.e., I think the new Renault probably is better car than last year's since I think Alonso is better than a 9th place driver, basically).
However, there comes a point where you have to say "Look, Alonso drove wonderfully those years ago but now his successor is doing better than he was at Renault, so far he has not been able to get the kind of results his predecessor's did when he got to Ferrari, and Ferrari is doing the worst in both WCC and WDC that they have any year in any recent history (except last where they only had one driver of course)." I think there's a place for pragmatism in comparing f1 drivers. To me this involves recognizing there's a point where past results are no longer sufficient basis for assumption that other drivers who are doing extremely well (particularly in inferior equipment) might not be just as good.
In other words, I think there's a point where, if a driver has once gotten great results but then doesn't for a while, the onus is on him
to show that he's better than the newer drivers who are getting better and better results all the time. Particularly in situations like Kubica where Kubica jumps right into Alonso's seat and takes the team to new level. Sure, it could just be Renault made miraculous improvements and Alonso has had terrible luck for years etc. However, for me the onus is on him to show that these things are the case. To me he hasn't whereas drivers like Kubica and Rosberg have been doing nothing but exceeding expectations with tremendous consistency. For me the question is more "what exactly are the reasons we think Alonso is better than some of these other drivers?"
