Yeah, kind of goes with car competitiveness (eg Vettel only scoring 1 victory in the same races that he gathered 8 wins in '11). '09 half the year was wasted, '10 and '11 were good cars, but not quite there with Red Bull, and not on the level of the '07 and '08 cars he drove when compared to the competition; and 2012 was largely wasted not by his own doing. Look at Alonso, I guess from a pure statistical view his last few years have not been impressive at all. 18 victories in a 3 year period, but since '07 only another 11. I doubt many would have expected that. Competitiveness changes all the time, and that will drive the stats.
Sure but someone was trying to say Hamilton's stats speak for themselves. His stats have been less than impressive over the last 4 years. In a way he is a victim of his own success stat wise from his first 2 years. His first two years were monsters and that is what built the initial "Lewis mania".
Alonso's stat's have been up and down over a long career, however his 33 podiums in the last 3 years compared to Lewis's 22 is one reason Alonso is held in high regard.
You can say Vettel has the Red Bull but you can also say that other driver's haven't gotten to drive for a team like McLaren their whole career either.
Again...my point was about stat's which I have never claimed to be the whole story. Peace.
