Removed the Snuggerud part because I don't fully disagree that there's risk there, but there is with any prospect.
Wanted to touch on the Schenn part being hard to move. While I don't think you could expect a substantial return for Schenn I think that there are alot of teams looking to move out from the rebuilding phase going towards contending that could benefit and would like to add a guy like Schenn. The issue at hand is we are also in that spot. We don't really need the cap space, we've proven with Steen that a guy like that can still be rostered in a contention window and does add value. I don't really forsee them moving on from Schenn, but I do think eventually they're going to have to remove the captaincy from him and hand it over to Thomas. Your guess is as good as mine about how that plays out, and honestly with Steen taking over, there's a possibility it doesn't play out. it just seems like a rather logical move.
I think the most logical player to move is Saad, and i'm not really sure the organization cares about stockpiling the prospect pool as much as they did the last couple of years. In terms of his clause, I think it would be fairly easy if it got to the point to convince him that moving to a contender is a better career move for him than staying here for a year and a half to have his ice time limited because we need to see this younger core getting meaningful minutes.
The other players you listed, save Faulk/Leddy which I don't think they'd be someone that we would move, aren't really too meaningful in terms of where we want to be in the next couple of years. They were all pretty low risk bets. I don't think you'd see the Blues moving out Sunny, but instead moving him into an extra forward role, which for the player may not be the best situation, but at least he's still here where he wanted to be.
