What if Hoffman only resigns for a one year contract?? In that case - a very possible situation - he'd appear even less likely to resign.
If there was a decent chance of that situation coming to fruition I would hope Murray would have the foresight to trade Hoffman for assets before it happened. I am assuming you are talking about Hoffman going to arbitration again, because if he is re-signed it will almost certainly be on a long-term contract. Given how poorly Hoffman fared the last time he went that route, I have a hard time believing he'd elect for arbitration again.
Shattenkirk currently plays 2nd pairing. We heard the same arguments about Bobby Ryan, fact is this team treats its players extremely well and has a reputation for doing so. Shattenkirk would instantly enter our leadership core as an important piece. As I addressed above, money is not a concern whatsoever. We have a ton opening up, and that money should absolutely be spent on D.
Finally, there's a team more desperate for a high end DMan than we are? News to me.
Shattenkirk does play on the 2nd pairing in St.Louis, but he probably isn't going to re-sign in St.Louis, which is a major reason why he may be traded, so doesn't that work against your argument? In regards to Ryan, we had to give him fair market value, or possibly even more than that to keep him here long-term. If we were to do that for Shattenkirk, we'd be looking at 7M+ long-term, which just doesn't work for us capwise, given that we have to re-sign Hoffman, Turris, Stone and Zibanejad pretty soon.
And yes there are teams that need a top pairing RD more than the Sens, a team with the best RD in the game, and a promising future down the right side with Karlsson, Ceci and Wideman all being right-shot defensemen that are a part of our future plans.
So all the complaints against Murray not getting a top 4 D are completely moot? If we offer him as much as any other team, he'd absolutely consider us. We're one of the few teams that will be able to offer him a big contract without worrying about losing any top players. I see no reason to back up your claims.
Murray has had opportunities to acquire a top 4 D (as someone already suggested: Leddy, Petry, Boychuk etc..). He doesn't have to go out and gut this team's young depth and handicap us financially in order to acquire a defenseman.
I simply don't think it's a good idea to deal a package of large value for a player that is nowhere near a lock to remain here long-term. We're not at a contending level just yet, so making a risky deal for a top defenseman just doesn't make sense.
