Best driver combination, best car... and we still can't win consistently. It really Sucks. I'm gonna need a new TV after finger boy wins his third WDC and WCC for RBR, that's for sure.
Button just a good driver, nothing spceial, he is far from his best form. Hamilton doesn't have motivation since second half of 2010. Both drivers are "broken". The car is the best, but key to this season is perfect setup and optimal balance. If you succeeded in both components, you can win even on Williams or Sauber (with a little luck). Button is very sensitive to setup, so it is very difficult to him to find a good (even not perfect) balance. Lewis again, doesn't have enough motivation, plus very often he chooses wrong direction in car setup.
McLaren needs changes, and I think Lewis' desertion is a good change. No sense to keep him if he doesn't enjoy driving McLaren anymore. If he had motivation like in 2009, he would be unbeaten in 2011 and 2012. Very sory for both: Lewis and McLaren.
