I have explained Calgary.
The Isles cannot be sacrificed because they are MINE. On almost anyone else's comparable list I would expect them to be, if not doomed, at least highly suspect.
The real problem is Washington. On the one hand Washington is a stupid place (take it from me). And the Caps are after the Isles so they would be safe to cut. BUT. My youthful awareness of the NHL includes the Caps. They stay, although they are shakey.
The list is actually logically consistent.
The Caps organization can go frak themselves. They do nothing to support youth hockey in the area (but they really support roller hockey).
Plus there is the Cult of Ovechkin.
