The NHL is investigating the circumstances behind former coach Mike Babcock’s resignation from the Columbus Blue Jackets, according to reporting. Babcock resigned before coaching a single game in Columbus. Nearly three years later, the league is seeking information on why he left the team. The investigation is described as being prompted by developments involving the Edmonton Oilers, alongside a renewed push from the NHL Players’ Association (NHLPA) for answers. The NHLPA is reported to be actively seeking clarification about the resignation and why it occurred. While the reports do not detail specific findings or potential conclusions, they indicate that the NHL has opened an inquiry and is looking into the matter long after the initial resignation. The reports also frame the NHLPA’s involvement as a key factor in forcing the issue to be revisited, rather than allowing it to remain unresolved. The NHL investigation is ongoing and the outcomes have not been reported.
