Three chances to clinch a playoff spot ended in whiffs and some in the fan base are panicking (as Sharks fans are want to do). The Sharks aren’t clutch, they say. The Sharks can’t win without Marc Edouard Vlasic, they say. On the other hand, we’d argue that the big problem this week, aside from running into a hot goalie against St. Louis, was a return of mental errors and iffy goalie play. So listen in as we talk about what the Sharks need to do to have success when the playoffs arrive. Hint: some of it is out of their hands.
