Good points, but as a one-for-one deal it's still an overpay. Duchene has flatlined, scoring 55, 59, and 41 points over three seasons. I get the argument that he needs a 'change of scenery,' but the trade should be predicated on him producing at current levels, not reverting back to his PPG pace of four years ago. I suppose the real question is found in your third sentence: IF this is the only way to upgrade at C, should we do it? I'd be interested in hearing the board's thoughts on the question, phrased like that.
It's also interesting to ask: what if they make this trade, and Duchene plods along at his usual 55-point clip while Galy reverts to being PPG C he was before the injury? Does Bergevin survive the PR disaster this would represent, fresh on the heels of the totally pointless and fan-alienating Subban trade?
