I doubt that exchanging that one win with a 2nd place would make a significant impact on the table. The difference between Vettel and Webber is almost two places (1.56 to 3.33), while the difference between Alonso and Massa is almost three places (3.44 to 6.38). So Massa indeed did a worse job compared to Alonso than Webber did compared to Vettel.he has? Well his figures are a bit massaged by his win on Sunday which I believe Ninja you thought was a set up anyways.
I'd say Massa and Webber had equally bad seasons
Btw an interesting stat was not since I think Monza 2010
the podium has been filled by the drivers in the top 5 this year and last year...only thing missing is one of them is not a world champion - Webber from the party of 5
