Maple Leafs’ GM Brad Treliving may have to call Flyers’ GM Danny Briere because after 2024 the defensive core of the Leafs will be shot. Six of Toronto’s eight defensemen will be unrestricted free agents with one restricted free agent. That may seem far away but in the present day, the Leafs’ blueline has been flagged with injuries. Sean Walker and Rasmus Ristolainen may be two great additions to an original six club in a blockbuster trade even before the NHL Trade Deadline.
