Hey, the A's won a championship. The Raiders won multiple championships. The Sharks have made the playoffs a bunch of times, where half the teams do.
Yes, the fans are used to the "Silicon Valley good life, the best of everything," so they're not accustomed to mediocrity, or in this case much worse. That said, while the Sharks may have been well managed for many years, that certainly does not apply the last four or five years, where Wilson made suicidal trades and contract moves. The results were predictable (and oft mentioned and warned against here), and now they have arrived. Even in the best of circumstances it would take years of very painful rebuilding. but the Sharks have made it much worse by hiring an amateur, whose hiring smacks of political correctness more than hockey acumen. Mike Grier has no credentials to be an NHL GM, especially in a very challenging situation, such as faced by the Sharks, thanks to Doug Wilson. This wasn't a job for someone with training wheels.
It doesn't appear that this situation, at least as I see it, will just calmly resolve itself with the passage of time. I see an eruption in the future. In fact, an eruption is necessary, or they're going to wallow aimlessly for an endless period of time. The main problem is that ownership is and has been clueless about hockey. They should have stuck to software.
