That's just not true. While I don't think he will get a big return, he is a legit NHL backup that has really good numbers as a 1A in MTL playing behind a rookie defense core and a team that doesn't play defense.
I personally wouldn't trade him if I'm MTL, at 27 there could be a lot of upside and we don't have a better goalie in the wings. Conversely, I wouldn't trade for him unless dirt cheap if I'm Edmonton, as his upside is still TBD and they should be going after a legit, proven, top 10 #1G.
But he is def a good player, far better than any Oilers G, and you definitively don't know a thing about him.
