It's not only in his control, and so Dubas shouldn't be the only one held accountable in any situation, frankly. Everyone should understand that there are multiple parties involved, seemingly with different goals - The outcome of such a scenario can't be put solely on one side, in my opinion, at least not with the information we fans currently have access to.
Unfortunately, because I don't have enough info regarding contract negotiations or trade offers, I can't say when "urgency" kicks in for me - All I'm planning to do (for now, at least) is keep holding out hope that Willy signs a contract that fits in our cap structure and remains a Leaf for a long time. My worst case scenarios, though, are getting terrible trade value for him, or signing him to a deal that we know handcuffs our future, and any urgency I have would go towards avoiding those outcomes.
