Brackett apparently being on the way out brings to mind the purge of 2015.
Gilman, a smart guy, CBA and cap guru, job had been partly to tell Gillis when he was going to make a mistake. Asset management was his strength. It isn't a high priority for the current management group so he didn't fit in.
Henning, who made the Utica Comets a force to be reckoned with, 2nd best team in the AHL.
Eric Crawford, often the forgotten man. In the summer of 2013 the Canucks took the long-overdue step of moving someone above Ron Delorme. While Delorme kept (at the time) his title of Director of Amateur Scouting, Crawford was moved above him as Director of Player Development. Crawford ran the draft for the Canucks for only one season, 2014. Besides first rounders Virtanen and McCann the Canucks drafted Thatcher Demko, Nikita Tryamkin and Gustav Forsling that summer. The Canucks haven't gotten much out of that draft (McCann was one of the assets given away for Gudbranson, Tryamkin was unhappy with the Canucks and returned to Russia, Forsling was traded to Chicago where he spent three seasons as a marginal NHL/AHL tweener) but it was a solid draft. Of course, the guy who engineered that draft was fired the next summer and the players he drafted were for the most part not kept around.
Just as the views of Gilman, Henning and Crawford weren't valued by the new management regime, it seems pretty much inevitable that Brackett would go the same way. Benning and Weisbrod do scouting and Brackett's opinion, while reportedly valued by Linden, was perhaps not so valued by Benning so just as a year after Gillis' departure his smart guys were gone, now, a year after Linden's departure his guy, considered by the consensus on this forum to be intelligent and competent, is about to be gone.
The Canucks came up with Brackett as a competent replacement for Crawford in amateur scouting. They may or may not come up with a competent replacement for Brackett. The loss, assuming there is one, won't be apparent right away.
