Management is going to be severely handcuffed when it comes to acquiring players with term, which is concerning given the team has significant holes at top 6 LW, 3C, and bottom 6 depth.
Next summer Rielly's raise kicks in, both Sandin/Liljegren will need bridge contracts, and Campbell's cheap deal expires. If Campbell takes you deep like they believe he can, he will need a significant raise. If he fails, it's clear they need an upgrade. Regardless, you will not enter 2022-2023 with a starter making only 1.65m.
Hypothetically, even by cutting ties with Muzzin next summer via trade, that will only be enough to cover the above raises, let alone replacing your #2 D. Don't see any way to improve the team's depth long-term without trading a core piece.
