I think if the Sharks could play good hard-nosed hockey for an entire game (instead of one period like they always do), then they have a very stong chance at the Stanley Cup. If they don't step their physical game up a little more, they won't win. You need to be gritty and willing to get dirty to win a Stanley Cup and the Sharks lack that "killer instinct".
But I went to the game last Friday and they played very well.
With that said....Go Pens!
