I don't think anyone can realistically argue Schumacher, Alonso and Hamilton are unproven. The quality of this trio is unquestionable and all have been the best on the grid at various times.
Greater question marks exist over Raikkonen, Button and Vettel who have never quite stood out from the rest in the same way*
*the RB7 being the real star last year
you kidding me right?? kimi nvr stood out??
how he drag the 2002 mclaren car to title fight with Schumacher in 2003 despite still driving on old version chassis and finished 2 points behind Schumacher.........
something that alonso did this season but got hail as god....kimi ???
MOST UNDERRATED DRIVER EVER..LMAO
I think Kimi is the guy who in my opinion has, over his career, deserved to be a multiple WDC winner but hasn't been able to achieve that because of reliability or various other issues. I say this because he has come very close twice to winning the WDC losing out to Schumacher and Alonso respectively.
The same can not be said for Lewis and JB.
I am not saying that Lewis and JB are not "proven" champions, all I am saying is that Kimi should have won it more than once and I believe he still has a chance.
