I can't believe you are talking about trading Coyle. What have Greenway and Tuch done in the NHL? Whatever happened to earning a spot?
Even Wayne Gretzky was traded. It's about what you get in return, not what have Tuch and Greenway done to get a spot.
Who's to say if you trade Coyle it even opens up that spot for them? What if the asset in return takes that spot?
There is value enough out there for ANYONE to be traded if the right offer is made.
