I agree on them not being traded, but if there was a trade to be made for an "answer" in net as the post I replied to mentioned, these are the only guys that even have minuscule chance of being traded that qualify for that imo. The rationale for MTL would be them wanting to give Primeau a shot at being their future in net and having to choose between Allen and Montembeault, although I had them flipped on who was the pending UFA (Montembeault is another intriguing option who has a similar cap hit to Lindgren and wouldn't be cost prohibitive).
Lindgren would be interesting as well if Copley didn't turn it around/Rittich can't step up. Connor Ingram is another guy who costs about 700-800k more than those two, but likely falls into a similar status as Vejmelka depending on if they want to extend the latter past next season.
