I'll repeat the same thing I wrote in many other threads: I think he needs to be kept in Montreal, since the D is very, very young. We have a 1st and a 2nd year player on the top 4 already. (ie, Struble and Guhle)
I'd only move him for a high price, that gives Montreal both assets for the future and assets to bolster the blueline in the short term; that's likely a 1st and a 2nd (ie, the 1st for the long-term, the 2nd to replace Savard over the summer without overpaying on the UFA market).
I'd really rather just keep him for one more year, and move him for a 2nd (or more?) in a year, at the 2025 deadline.
