I'm somewhat surprised that it was Montreal and not Arizona that Niku chose to play for. There's a massive opportunity in the latter location to get some playing time that may not be available anywhere else.
* Niku has time with Chiarot with the Jets
* Chiarot's previous partner is on LTIR (Weber)
* Habs need a offensive puck mover who is not 100% in the development stage (age 18-22 vs 25+).
* Niku needs a mature and trusted physical guy to be paired up with and I believe the Jets had difficulty with finding this fit for him. Habs have a few of these types.
* Niku gets a very solid 2 way salary for the AHL.
He has a better chance at proving his worth with the Habs vs the Coyotes. He still has to fight for that spot with Chiarot with Norlinder and Wideman but he's got a fair chance at earning that spot and the past experience with Chiarot will help.
Maybe he knows Lehkonen and Armia well? Lehkonen is one year older and Armia is 3 years older and did their time with the Jets overlap? Not sure but if so, all these things add up to Niku signing with the Habs.
