OP is from St.Louis. So it seems from HFB perspective the Blues were asking to put Bozak in the deal. Obviously you can disagree with the intention of OP.
From a Devils perspective Bozak is a cap dump and would not have positive trade value. There are enough teams out there with dire need for cap space, that would treat a similar contract as a cap dump and offer a team with cap space an asset for accepting said contract. If the Blues aren't that team fine. Just remove Bozak from the equation and go on from there.
Thats what I'm trying to say Dunn is worth a first +. If we decide to move Dunn that's what it will take. Putting bozak with him is just not happening. Especially when bozaks contract is up after this year
