He'll probably come in, but TBH, another year of USHL hockey is exactly what he needs. Clearly the league was very tough for him this year. If we need a dman bad (which we don't obviously), I'd flip an over ager like Attard to come in.
Back to Frisch. I just think it would benefit him to log a ton of minutes (in all situations) and come in more polished and extend his development cycle by a year.
