The issue with this we simply haven't seen enough of Power to know what he's worth. Usually when you 'pay for future performance' you get some sort of discount by signing before they breakout. Similar to what he did with Thompson, they felt there was upside there, took a bit of a risk by signing him long term early on the back of a strong season.
You don't make them the 15th highest paid defensemen in the league. It's even worse when you consider that he was a 10.2c RFA, meaning he had absolutely zero leverage. This is the Samuelsson deal on steroids where you give out a long term deal with only 1 rookie season on paper.
I'm very curious what could have Power done this year that would have earned him a HIGHER contract next summer. He's not going to get PP1 time, and Dahlin is going to eat most of the choice O-zone starts, so Power isn't going to be an offensive dynamo. The comp here is Ekblad...but that Ekblad contract isn't good. He's had one strong season so far.
The obvious thing to do here would have been to bridge him this summer. a 2-3 year deal, in the 6M or so range, and deal with the the long term contract down the road a bit when you know who he is going to be in the NHL. Is he going to be a have a solid NHL career like Jay Bouwmeester, Erik Johnson, or Ekblad, or is he going to be an absolute Elite d-man. And then figure out his contract. Right now, it can literally go either way. But we're going to be paying him like a top tier one regardless.
Just another dumb decision by Adams.
