I've literally just been thinking about how soccer has Red Bull and Man City groups that buy a bunch of teams all over the world, and kind of filter players up the ladder. It's pretty much a non-starter right now for hockey.
I mean, an owner could have a team in the NHL and another in Sweden, for example, but outside of maybe sharing scouting and some business expertise, there isn't too much benefit, I don't think. The game is absolutely tiny when you compare it to soccer, or the potential for growth in basketball.
It makes sense for soccer teams to truly scout worldwide, even getting involved in setting up academies in Africa, etc.
With the NHL draft, there's a disincentive for owners to use their own capital to 'create' more players, and the game is already too expensive in the US. In the pre-draft era, major junior teams were sponsored by NHL teams, and the more money you spent, the more access to prospects you had.
The NBA makes sense to grow internationally because the cost of entry is so low. They basically just need a ball and hoop.
As I've pointed out, the entire state of Florida has 17 local rinks. The business model of this apparently isn't appealing enough to the world's leader in GDP. You can only really 'grow' the game in hyper-specific markets that can afford $30 sticks.
Maybe the game would organically explode in popularity in, like, the Philippines, but because they don't have the economy, we'll never know.
