You're getting a young top two center for a package built around an expiring contract and your complaint is
Mark Fayne? Oi. You're looking that gift horse so far down the mouth you can see its tonsils.
Except they're not getting a young #2C for Shatty, they're getting him for Shatty + Lehtera (slightly overpaid, but not by much and still a quality player) + Ty Rattie. Fayne does nothing for STL. He's essentially a cap dump for EDM. IMO, that's a lot for RNH. I like RNH, but I feel that EDM overpaid to sign him up long-term. If RNH's contract was 5M per instead of 6M, I'd say that he's worth Shatty with a provisional deal agreed upon i.e. trade and sign.
But Shattenkirk isn't interested in signing an extension with Edmonton. If he was open to that, Taylor Hall would be on the Blues right now.
I doubt it. I don't think STL wants to keep Shatty in the West and I don't think EDM gives up that much for an unsigned Shatty. Personally, I'm not convinced that Larsson becomes anything more then a #2D. However, it seems that PCs options were limited. I wouldn't be surprised to hear that STL and ANA were quickly putting the phone down on calls from EDM.
