How Much Fan-Equity Does SF Giants Have?

How much time and patience does two World Championship give a club struggling? We've always said that we would kill for just one World Championship in our lifetime, but now we have two in a three-year span. Having said that, how much fan-equity and goodwill has the club established? How many years will fans give the club to regroup and field a pennant contending team? Some have said one, others have said five, when a few others have said 10-15 years. How much time are you willing to give?
