As Devils fan, I agree with this. Think Davies will be an NHL player in Nashville. Not the type of player that you will regret trading for PK Subban, but a productive player.
I think an underrated piece of this deal for NJ is the inclusion of Santini. With TWO years remaining at 1.4 this is a bad contract, despite the fact that the $ is not prohibitive.
Santini has been bad, has limited ceiling and that contract was a head scratcher in the first place. Its negative value for NJ, as Santini appeared to be headed to a spot on waivers, Binghampton or at best the press box - and that was before the Subban add.
So taking into account the unloading of that contract makes it more doable for the Devils financially.
