I think that's the most it would cost. I'd personally not do it as he is more of a defensive dman but he can be productive with the right partner. He and Marino are a good matchup defensive pairing that could free up Hamilton's pairing for more O zone deployment.
Luke-Nemec go vroom vroom
Pettersson-Marino shutdown
Siegs-Hamilton offensive role
if you're down 1 you see a lot more of Luke Nemec and Hamilton
If you're up 1 you see a lot more of Siegs Pettersson Marino
Overall they all get about 20 minutes a night on average, changing game to game.
At least that's how I'd play it.
If Pettersson gets to UFA and NJD could get him at 5 mill AAV I would be jumping for joy.
I'd go as high as the severson price for him if I don't have to give up draft capital but who knows what the market looks like. HIm being a lefty probably worsens his market
