Mtl would trade Patioretty for Vatanen or Burcher and a 1st pick 2018.

MTL fans are hilarious. Have been searching for quality centers, yet they could get a top 6 center here, potentially another one, plus a pick and another prospect here.

Zacha is your 2nd line center by default. Your C1 should be Hall, C2 should be Hischier and Zacha C3. You hope to get a LW1 with Pacioretty vs a C3??? Other young players you added are too young to know what they will become but Mtl has way too many bottom 6 players. If you need a top 6 LW you need to give a top 6 or a top pair defenseman.
You have to give something to get something.

I don't like the Devils, I'm just saying Devils would be worse off trading Vatanen and a 1st for Patches. MTL won't be able to compete during what window patches has left of his prime, so I wouldn't be so quick to turn down a chance to get better and younger in a deal for him. Also, Hall is a wing, not a center.

Why don't you trade Butcher for Pacioretty, keep your money for Hickey and trade a 3rd pick for Brad Hunt in Vegas. at 650K$ he's a bargain and can play LD and RD.
Keep severson and forget about Getzlaf. Keep your money and get a UFA #2 Center:
Stastny @ 6 or 7M$;
Bozak @ 4M$
Riley Nash @ 4M$
and the money you had for Hickey, add it to J. Carlson contract. There is a team out there who will probably give him as much as 9M$. With the parity, he's a taker.
