I think currently Williams needs to restructure itself to that of the modern day works teams such as mercedes and ferrari and now renault; who are in the process of restructuring to put up a title challenge.
Paddy is still fairly new to the team, and i think by next year Williams will be in better shape. Now it's just teething pains with the new car. Soon enough they will figure out the strengths and weaknesses of the current organization structure and produce a better operation and team next year.
This year's car is strangely a poor performer, but i believe this is down to it being very new. Next year should see an improvement as we have seen when mercedes improved on their 2012 to 2013 car and then the 2014 car.
As for the drivers and Russian links, this wont change any time soon. I believe Paddy's wife is a Russian actress, so there is probably a lot of behind the scenes links with Russia for Paddy.
