One reason the Kings production is considered low is because of those horrible first 3 games. Without those, the Kings are producing at a pace of 2.83 goals per game, which is right around 6th in the league.
They also gave up 12 goals in those 3 games. which makes their defensive numbers even more impressive.
Over the last 24 games, the Kings have scored 2.83 GF/G and allowed 1.83 GA/G. That's pretty impressive, considering they haven't been all that lucky. The teams that have impressed the most with that stat are MTL, WAS, DAL, and the NYR. They are also 4 of the 5 highest PDO's in the league.
The point is, outside of a crappy first few games, the Kings have been absolutely one of the elite teams in the league. And they've been doing it without getting the bounces.
As fans, we always think of something as being wrong, but think about this. Outside of those first few games, has their been a game the Kings have been out of with no chance to win? They've lost one game since then by more than one goal, and Chicago scored a SHG with a minute and a half left to seal it. That's incredible and shows they just don't take nights off like they used to. This is a hungry team.
