I feel pretty good about Niku over the last 5 to 6 games. I think it is obvious that he is starting to finally get comfortable. He only needs experience and confidence. I'm confident he is a dangerous top-4 offensive defenseman at this time of the year in one year and the league is going to start recognizing him for it.
Definitely agree with the bolded. I am hopeful for the second half of your statement but time will tell on that.
I will also humbly submit that we ought to give credit to the coaching staff, specifically Charlie Huddy, on these small but important steps forward. The style and messaging to the the defencemen this year has been a critical component in development for guys like Niku, Poolman, Pionk, and even Bitetto. Granted we do not have a first tier D-Corps and the team has struggled at times for sure, but it is clear to me that the coaching staff have had to make their own adjustments. They allow each individual to go out and do the thing that are really good at, whatever that may be (playmaking, cocking shots, simple passes) and allow breathing room for mistakes. To be malleable and learn as a unit. This is a bit of a different philosophy than it has been since Maurice has taken over and a guy like Niku can really benefit from this, provided he remains being open to be taught and mentored.
