Is it though? It's not like it's mostly from bad luck. This is 9 games of them looking sloppy as f*** with the puck in their own end, goaltenders that look like they aren't capable of mitigating leaky defense, and the PK looking mediocre.
Their outrageous offensive numbers are the result of a PP that is clicking at nearly 45%...even the best PP's in the history of the sport have not maintained that kind of success for an entire season, so that's something you should expect to see come down even if they continue to play great there.
