I'm really not sure why you think a child of a Canadian hockey player, who played in the CHL would be adverse to sending their own kids there. It's not like he's been around MN for a decade to get into the romanticized nature of HS hockey around here.
Hell Tkachuk is an American who played HS hockey, and he sent his kids to the CHL.
Well, he's been in the States for close to 15 years. His kids were born here, and are American. Maybe he is and his wife are, also? I'm guessing they are. It does depend on his kids, and whether they are academically inclined, even a little bit. If so, you want to be doing the HS(i.e. Shattuck, STA, or town team, i.e. Edina, EP, Tonka, Lakeville, etc..), then college. Most parents, especially ones with $$, realize how important education is, and how tough it is to make it and stay in the NHL. It's really hard riding on buses hundreds of miles at a time in the WHL, and trying to get your classwork done at a high level of proficiency. Also, CHL hockey is a business, not so much a training ground for players. USA hockey is more based on the European model that develops skills, and favors practice time over games. Most former pros that i know are all about having their kids develop skills, not getting their kids faceplanted into the boards in Lethbridge.
You can always find examples of ex NHL'ers that send their kids to the CHL. In most cases, it's because their kids simply don't have the academic chops to go far in school....and by that, I mean it's tough for them to finish even HS.
Again, it's a hard road. The opposite case is where someone like Mittelstadt and Brinkman(Edina Junior 2019) turn down chances for CHL and USNDP because they simply don't want to leave home yet, and when they do finish HS go 15 miles down the road to the U. There's something to be said for that. It's not like the training is inferior, and they can always play high level competitive games in the summer/USHL outside of HS should they feel the need for some more competition.
