I dont think the Devils are in go all in mode but I think they have reached the point where they want to be in the post season, and it looks like they are buyers. They need a 3C and Evans can fit that. They also apparently want some secondary scoring and while Anderson would not be their 1st or maybe even 2nd choice, he could help them and we could retain. They dont have a 1st in 2025 and we could trade them the Calgary 1st, though I dont think picks is what they are looking for. Add in Mailloux who is big and talented offensively though shaky on D. So our offer is essentially 3 mid- late firsts ( Calgary's and the cost for Evans and Mailloux 31st overall ) and Anderson.
Nemec is not a rehabilitation project he just hasnt been able to be one of the 6 best. And they may want one very good quality piece back instead of a bag of lower quality assets. However, Nemec is getting annoyed and may be at the point of requesting a trade which will likely create an issue, though Nemec really has no leverage as he is signed until 2026. So they really have no pressure to trade him.
Would I take that package for Nemec ? No, but Im not a GM with some pressure to get into the post season, and the package isnt some awful low ball offer. You never know.
And maybe we dont want Nemec for that price and prefer to go for a veteran D who can really help over the next 4-5 years.
