As for the AT&T Williams team it was a great drive from Nico to see him come home in fifth and secure four points fro the team. He was able to push so that after his second stop he would come back out in front of the Brawn cars, even with the Safety Car. Kazuki's race was not of any merit and his days at Williams should be numbered.
