The Boston Bruins were among the best teams in the NHL the past few seasons. They still have much of their core together heading into next season, except for their left defencemen. While the exceptional line of Brad Marchand, Patrice Bergeron and David Pastrnak is locked up for two more seasons, Torey Krug and Zdeno Chara will be free agents next week.
So, the Bruins could certainly use a left defenceman who can help right now. The Flames are pretty deep at that position with Mark Giordano, Noah Hanifin, Juuso Valimaki and Oliver Kylington as well as freshly signed prospects Connor Mackey and Colton Poolman.
If the Flames were to part with a guy like Hanifin, they’d still have solid depth at the position, and could fill another need with the trade.
The Bruins have been rumoured to be looking at signing Taylor Hall. If so, a player that could be on the way out is Jake DeBrusk. He is a gritty, fast, left winger who can score goals. The Flames already have Matthew Tkachuk and Johnny Gaudreau at left wing, but DeBrusk could transition to the right side.
