BTW a Winnipeg Jets fan was at AATJ and the discussion was about possibly having to give up Mercer to get Hellebuyck....
He stated this :
Ok, let's hammer out the details for our team's GMs.
Seems the Devils would be down to 10 forwards if they trade Mercer, so there is a need there. Not familiar with how many of your prospects are likely to jump into the bottom 6, but the Jets could probably offer 23 yr old Gustafsson ($775k), a defensively responsible center that scored okay in the AHL, but that offense hasn't transitioned into bottom 6 scoring yet.
Don't see a need on defense, but NJ may have interest in 6'6" LHD Stanley (unsigned RFA). He's 25 and could provide some size/depth, if the team needs it.
The Devils are tight against the cap. They’re also, arguably, a goaltender away from winning a Cup. Do they have enough room left to get the last big piece they need to win the Stanley Cup this season?

Not feeling in trading away Mercer...at all...but that may have to be the price (along with Vanacek going back, 50% retained hopefully) if we want Hellebuyck (or rather if Fitz wants Hellebuyck badly enough).
