To me it seems like Williams have on years & off years.
In 2010, they finished sixth in the Constructors Championship with 69 Points.
In 2011, they finished ninth with a dismal 5 Points.
In 2012, they finished eighth in the Constructors Championship with a car capable of finishing at least 6th, probably 5th.
Many people blame Maldonado for the failure to finish higher in the Championship, but I think that is undeserved. He did what was expected of him & even won a race.
If it was not for him Williams might not even be here today. Many people seem to forget that he brought $46 Million in sponsorship to Williams in 2012 alone.
Also if Hamilton hadn’t shunted Maldonado off track at the Monaco Grand Prix in 2011 he would have scored twice as many points as Barrichello in the 2011 season.
