What's the purpose of this thread? The Coyotes are a rebuilding team. They're in the market for young players to build a core around. They aren't close to being a playoff team.
I have no idea why some Blues fans even brought up Shattenkirk. The only player the Blues would want from the Coyotes right now would be Domi, who is part of their young core I just talked about. The Coyotes are looking to add more players like Domi, not get rid of them.
The Blues are looking to trade Shattenkirk for an upgrade right NOW, not a future upgrade, so that throws out trading Shattenkirk for prospects or picks, and basically means Arizona is probably one of the bottom 5 trade targets for him.
