The Chicago Wolves are run independently from the St. Louis Blues despite being the Blues' AHL affiliate. They tend to do their own thing as far as personnel, coaching philosophies, system, playing time, etc - so this hire isn't on the Blues.
However, it is a pretty decent one for some of the Blues' young prospects.
The Wolves hired Craig Berube as head coach today, announcing his new two-year contract deal. After two years coaching the Philadelphia Flyers, Berube finished with a 75-58-28 regular season record. He has 13 years coaching experience total within the Flyers organization. He was assistant coach from 2006-2013 before taking over head coaching duties, and also spent two years as head coach of the Phantoms, as well as two years as an assistant coach there.
How well his coaching philosophy will translate into success for the Blues' prospects remains to be seen, but it's Chicago's choosing and Chicago's doing. Hopefully the Blues will benefit from it.
