Ummm nope.. We don't have the same youth level development and cannot tap into it. Canadians can access D1 scholarships but they are not as readily available for international students.
I mean, our top basketball talent all goes to the US as well. Sometimes at the high school level (a friend of mine's son goes to prep school in Texas for basketball, just as my colleague's son went to prep school on the East Coast for hockey).
My wife played provincial level soccer, and all of her teammates ended up in the NCAA. Quite a few didn't stay because the pressure was immense at the varsity level at sporting schools and they really don't put much of a premium on their education.
At the very highest level, I think our top players will always end up there or overseas and we do have the capacity to tap into the US at a level that the rest of the world can't or won't. (geographic and cultural proximity etc.)
The NWSL also favours American development over Canadians, so if you are a bubble players where do you go to develop? This is where we need the infrastructure and Canadians women's pro league. A league designed for providing Canadians players with more opportunity at a high level.
I get what you are saying about bubble players and opportunity, but I still doubt that you'll ever see our very best play at home in their prime when there are better teams elsewhere.
Is the idea that Canada will have a league that rivals the European Champions League or the NWSL?
No, that would never ever happen. It'll be a nice feeder league and good for the sport but I don't know how much impact it would have on our high-end talent and the national side.
Where I think the investment really needs to be made is in youth soccer. I'd put 90% of my resources into that, particularly the development of qualified coaches and better fields.
