I liked Perez but replacing him with Kevin has been vindicated as clearly the right thing to do. The only Mercedes powered cars not to get in the top ten for quali were Button and Perez....makes you wonder about the 'badness' of that 2013 McLaren.
There it is in a nutshell - he difference between mediocre and real ambition
Same setup as last year without Kev, would have both McLarens qualifying in 12th and 13th, take away the dnfs in front, remove the sharp PITWALL strategy and you have Button dropping a place at the start and lucky to finish where he started. Perez would have gained a few places as he actually overtakes on track but if he had started behind Button would not be allowed to
So last years McLaren would finish the race 11th and 12th and we would all think the car was nowhere near the second best
This year Kev qualified at the front and maxed the car, Buttons achievement was in making no mistakes and driving within the car
