I'll copy the post I made in our GDT today here as well.
So I'm looking at some stats over the last 3 games, because apparently I'm a masochist. Here is what has stood out to me.
Sharks have 101 Shots For and 66 Shots Against to combine for a 60.48% SF%. This is absurdly high and obviously unsustainable as the top team last year had 54%. Corsi% and Fenwick% are similarly above 60%.
Sharks have 98 Scoring Chances for and 70 against, but only have 4 SCGF vs 9 SCGA. Shooting percentage on scoring chances is 4% for and 13% against. League average last year was about 8.5%.
Sharks have 39 High Danger Chances for and 33 against, but only have 2 HDGF vs 7 HDGA. Shooting percentage on high danger chances is 5% for and 21% against. League average last year was about 14%.
Sharks have the leagues worst PDO so far, at 0.883. This is a combined 4.95% shooting percentage and 83.33% save percentage. League average last year was about 9% shooting and 91% save (for a PDO of 1.000 obviously). By the end of the season its rare to have a team below 0.970 or above 1.03 PDO. So a combined 3% shooting and save percent is extremely uncommon, the Sharks are a combined 12% just 3 games in.
The good to take out of this is that most people believe shooting percentage (and therefore PDO) is largely based on luck. If that is the case, these games should be anomalies and the Shark's record will normalize over the 82 game season. The Sharks are getting incredibly unlucky on both ends of the ice through 3 games and there is very little reason to believe it will continue to be so. I get why it is frustrating, it seems the Sharks outplay (out shoot and chance) opponents and lose games way more than they should (I can name a number of playoff series lost in this manner).
TL;DR: The Sharks are statistically out playing their opponents by getting more shots, and more importantly more chances to score (both high danger and normal). However their shooting and save percentages are abysmal. They are essentially the anti-2017-vegas (because vegas had unsustainable PDO all last year). Their PDO will normalize over the next 79 games and their record will reflect that, so don't burn the town down just yet.
