If we want to take a step forward next year (and I believe Grier does), the options are pretty simple for 2C:
1. Re-sign Granlund. Ideally 2 years at high AAV to max our options.
2. Trade Granlund for "whatever you can get", and sign a lateral move C FA such as Tavares, Duchene, Marchand, Bennett (none of whom seem that likely or good fit)
3. Same as 2 but Sign a top of class W FA who can play with Smith or Wennberg, such as Rantanen, Marner, Zucker, Benn, Palmieri, Boeser
4. Don't do 2 or 3, and fail to take a step forward, gunning for McKenna/Verhoeff/Bjorck/whoever and risk being stuck in bottom-out mode
Since 2/3 don't feel that realistic, it feels like 1 is the go, but I'm placing a fair bit of trust in Grier to get the right thing done.
