Their depth and defense corps are mediocre, but have been for several years and they still managed to almost win their division a few seasons ago and then had a torrid start to last season. They can play better than this. The reason that they're not is the coaching.
Stevens sacrificed the one thing that they were good at--team defense--to try to get more goals that haven't come, so, now, the team is bad at scoring
and bad at defending. Nashville, when they wanted to move on from Trotz' defensive system, hired Laviolette, a coach known for employing a fast-paced offensive system. LA, when it wanted to move on from Sutter's defensive system, promoted the guy who managed the team's defense for 6 years under Sutter. It wasn't hard to guess that it would fail. When you want offense, you hire someone who knows offense, not someone who knows defense and then cross your fingers that sacrificing the thing that he knows will produce the thing that he doesn't.
The team has no identity anymore (unless being bad at everything is an identity) and nearly every player is underperforming. They may be old and slow, but they're getting chances, like all of the 2-on-1s last night. They're just either not getting shots (how they had so many 2-on-1s last night and failed to even register a shot, I don't know) or their shots are so bad that they don't beat even Garrett Sparks (who allowed 6 to CHI in his only other game this season). It looks like no one on the team has any confidence. It's natural for a few players, at any one time, to be slumping and low on confidence, but, when it's nearly the whole team, you have a coaching problem.
Their forwards suck so bad outside of Kopitar and Kempe.
Kempe is not good. His goal a few nights ago was his first since last January or so (yes, he was healthy last season and played the final 30-some games without scoring) and he's taken 6 minor penalties in 7 games so far, and at least half of those were in the offensive zone. He might become good in a year or two, but he's still a project and ought to be scratched tomorrow because of how undisciplined he was last night.
