Montreal is near the top of the league in 1-goal games, and have a 16-10-6 record in those games. While it's certainly possible they'll be sellers, I don't think it's a given. Any UFAs signed wouldn't necessarily be one-year deals for the purposes of flipping. If they do sell, Savard will be seen as a premium and not hard to move. They didn't have to retain on Monahan, got it done early, and got value that is better than some of the return this week.
I don't think there's a reason to be glass half empty here.
