If we're going to play the game of who DESERVES a championship, yep by all means give Massa the 2008 crown. But give Hamilton the 2007 crown, Rakkionen the 2003 championship, Hill the 1994 title, Prost (or was it Senna, I forget, the one that got ran of the road at japan anyway) the 1990 championship, Mansall the 1986 crown, and Stirling Moss the 1958 world championship.
In truth, if it goes to who DESERVED it in 2008 (i.e. Massa) then you may as well tear every F1 book you own in two.
