Agree 100%....however HS hockey is not going to do much for Hain anymore. The kid dominated....he would be challenged 10X more playing for the U18 team next year. But like other posters have mentioned, he probably won't leave. Hey, even our prized Boeser left after his junior year in high school. Should he have stayed for his senior year? No, high school hockey would do nothing for him; the grind of the USHL season would develop him much better.
This isn't a knock on MN HS hockey....because it's a great league. I'm talking specifically on this uber elite kids (MIddlestadt, Hain, McLauglin, etc).
