Hard disagree.
From 2020-21 until 2023-24, he was 28th in points per game among defensemen with at least 200GP. Offensively, that's low-end #1D kinda production. His advanced stats, defensively, have him pretty much middle of the pack. Certainly not the cream of the crop defensively, on the level of guys like Makar, Hedman, Heiskanen, etc., but he was never expected to be on that level, never played to that level and certainly not paid to that level.
We sold "low" because of our GM. Plain and simple. You really gonna tell me that Washington just suddenly realized one day he was a $9M AAV defenseman? He was 16th in points among defenseman the day he signed that contract. He wasn't even the top-scoring defenseman on his own team, at the time. Washington knew exactly what they were getting. You don't trade for guys like him without a plan to sign an extension.
Our guy blinked. We lost the trade badly. Nothing we can do about it now but this idea that we had to trade him for so much less than his real value is just absurd.
