I don't think he is an elite second line centre but I also don't think he is paid like one. The Stastny contract.. that is the going rate for veteran second line centres. For a guy who produces 50-60 points, with very strong defensive play, I don't think six million for two years is too much. We don't have a replacement. Yes he slows down in the playoffs, like everyone but Subban, Eller and perhaps Petry on this team. That shouldn't excuse him, but I don't think it makes sense to single him out either. And when he is your best player in your position of great need, when it is hardly very apparent that Staal, Backes or any centre available by trade would be an upgrade.. Plekanec on the team for the next bit becomes comfortable.
is it fair to wonder, given the current needs the Habs have, whether or not that 6M salary for the next 2 years would be better spent on a different, more impactful player?
It's not that Plekanec is a bad player, quite the opposite actually...but he's misused by the coaching staff and it's resulted in the GM overpaying him based on that usage.
