Yes his gameplay this year wasn't up to expectations, but can the Canadiens permit themselves to lose Mike Komisarek?
Granted, if he did refuse a 4M$ deal, it leaves Montreal in the uncomfortable position of either overpaying the 6'4'' behemoth or letting him go in the hopes of signing a F.A. that can support prime minutes. Looking at this summer's available unrestricted free agents, the list of top four defensemen isn't abondant and considering Montreal's current ownership situation and past failures to lure quality free agents... it leaves the Canadiens with no leverage to negociate with.
I find that you can anwser the problem by asking yourself this question : Are the Canadiens rebuilding or ajusting ?
If they are rebuilding, ok... don't overpay and let him test the market.
If they think that the team can still progress, well then i don't see any reason why a young 26 years old defensemen coming off a sub-par season should leave the organisation.
In a season filled with underachievement, i consider it unwise to label ANY of Montreal's players and hope that the Habs rather AJUST and give Komisarek want he wants, to a reasonnable extent of course but considering Hamrlik is paid 5.5M$... you can expect similar numbers and lots of Tabarnac's sounding from MTL.
