Take it for what it's worth, but Bruce Garrioch claimed that both Duchene's people and the Senators were interested in sitting down and talking things over, and that they would both meet up next week to talk a contract. There seemed to be an assumption that the Karlsson trade would be done by then. Randy Lee is currently suspended and the Senators were already short staffed compared to typical front offices. So this makes sense that they'd put Duchene on the back burner while dealing with what should be the most important trade in franchise history.
Garrioch is accused by some of being this org's mouth piece, but it's relevant info none the less. If both sides want to get something done, it should be pretty straight forward. The market for a C of Duchene's calibre has been set at around 8M give or take.
