Oshie is a rare story. A year in the USHL won't hurt him at all. The only thing is, if you bring a guy straight in from HS, he might be willing to spend an extra year at UND. Take Oshie for example there. If you make him play a year of USHL, he might have left after his sophomore season instead of his junior season. So, it's a risky move to bring him in early, but you might get that extra year out of a player if you think he can still develop at the WCHA instead of the USHL.
