As much as it pains me to say it, Karlsson may indirectly be a bit to blame.
He is a generational talent and I love him as a player. But he is overused and covers up too many weaknesses elsewhere.
I would much rather have 6 guys that I can depend on night in, night out than 1 superstar and 5 guys who can sort of kill time until EK gets back on the ice. Which is sort of what has happened.
Just IMHO, but if you could have a defence made up of solid middle pairing dmen, who could all play 20 minutes and played a reliable, simple game, who could move the puck up to the forwards, that would really help the offence.
Right now, we have one player who does whatever he wants, (let's face it, because he can), and the rest of the defence is a bit of an afterthought.
