I agree, Shatty has a great shot that Oil need and has a great i.q for a defenceman. Shattenkirk over Hamonic every day.
There is a ton of appeal in Hamonic in that he actually wants to play here (in theory). At any rate, if Snow will trade him here that means he wants to be here.
Shattenkirk would cost a ton because of that extra year attached and there would be no assurance that he would re-sign. We could ask the GM to talk to him beforehand, but that's a requirement of the trade then there's a miniscule chance it gets done. Shattenkirk would promise us nothing besides platitudes, because why would he commit so early? He will have a ton of power as a FA, and can find a lot of money and he could pick his destination.
To me, I like the idea of targeting Byfuglien as a UFA after trading for Hamonic. UFA has the benefit of really talking to him and making the conversation real with ink. Also of course we don't have to give up player assets.
