I appreciate your enthusiasm for him, but at this point he would probably very seriously consider any extension that guaranteed him 1 way money for 1 or more seasons.
He has been fantastic in his role, but he has shown nothing to the effect that he will be a top 6 forward or a star.
Expansion is coming soon, so if he can leverage his strong play and his obvious relationship with Green into another 2-3 years as a 4th liner/PP specialist, another 23 roster spots in the league might guarantee that he sticks around for longer.
