The Kings have the talent on offense. Their problem is Sutter's insistence on choking the life out of any offensive creativity. Instead of using world class talents like Kopitar and Carter, he wants his team to play like 4 grind lines.
Every coach has a shelf-life and generally the shelf-life of coaches is very short. Saw it with Laviolette here just this season. So I'm guessing that's what's happening with Sutter over there.
It's not all the coach though since that bottom six is pretty much entirely grinding types with little scoring capability and their top six isn't anything elite or special really, but they should definitely be better then this considering that they're healthy and their top six should be at least decent offensively.
