There were many rumors and several positions were in question, but it seems the organization has found its scapegoat. The names of Sheldon Keefe (head coach), Brendan Shanahan (President), and Mitch Marner, among others, are on everyone's lips.
At the time of writing, his replacement has not yet been identified, but the name to keep in mind is Guy Boucher, who was one of Keefe's assistants and has a lot of experience in the NHL.
