Lindholm rental = 1.5 (no retention)
Hanifin rental = 1.5 (no retention)
Mercer = 1.5 (young, nhl experience, pedigree, ironman streak, top 6 projection, can play C. selling low during mediocre year)
Swayman = 2 (expensive for a goalie due to age, importance to BOS)
2nd round pick = 0.5
Bahl = 0.5 (young, cheap, one more year at 1.05)
Calgary - Quality over quantity. Mercer will benefit immensely from heavy top 6 play with room to learn from mistakes during the rebuild. He will be a leader when the team is ready to compete again. If the Meier condition bumps the 1st to 2025, they receive the Devils' 2024 3rd as well.
In: Mercer, 1st, Bahl (+3)
Out: Lindholm, Hanifin (-3)
Boston - Lindholm extends and they bet on Ullmark staying sharp. Devils retain on Lindholm as needed.
In: Lindholm, 2nd (+2)
Out: Swayman (-2)
New Jersey - Mercer is a huge loss but the goaltending must be fixed at any cost. Hanifin is not extended; potentially weak LD is a next year problem. This is all made possible thanks to Dougie dying for our sins.
In: Swayman, Hanifin (+3.5)
Out: Mercer, 1st, 2nd, Bahl (-3.5)
Bruins probably aren't interested in Lindholm at the cost of their long-term future in net. This is likely a non-starter, but the exercise of trying to balance it can be fun hypothetically
I personally don't like Vladar but it's not a terrible option. They could grit their teeth and run with something in-house, or they could receive Daws instead of the 2nd. It shouldn't be too hard to find a serviceable backup right now.
