Don’t know if you can really blame poor development, when he had multiple injuries to his legs when his biggest strength was being a big, mobile defenseman. He then just got surpassed by Calgary adding or developing plenty of other impact D-men. Fully healthy we can ice any of Hanifin, Weegar, Zadorov, and Kylington on the left side, that’s a young and talented group.
Friendly reminder that he was waived because Gilbert, Stone, and Mackey all showed remarkably better than him this pre season. The odds of him finding similar success playing any of their roles this season is slim to none.
