The St. Louis Blues have had a working relationship with the Chicago Wolves since 2013. Despite the oddity of St. Louis having anything to do with Chicago, it has worked out fairly well.
The only bad thing about the relationship has been the results as a team. The Wolves made the second round of the playoffs in 2013-14.
The next year, they crashed out in the first round. Last season the Wolves missed the playoffs completely.
While the Blues were involved in some coaching decisions, they had no ownership in the Wolves. The Wolves clearly did not make decisions that would fly in the face of the Blues prospect plan, but they were well within their rights if they wanted to do so.
