I understand the ownership, and your list helps me add Winnipeg/Manitoba to the list, But that's not what I'm talking about. It's not OWNERSHIP that matters, it’s the OPERATIONS.
The Pegula's own the Sabres and the Rochester Americans. But they're an hour apart at different locations. Same organization, but two separate operations. However, the Sharks/Barracuda and Jets/Moose are like the European model: They have one "Campus" where two levels of teams practice and play. They have ONE Operation that covers both teams.
