Well, the Flames have plenty of cap space available, they could take on unsavory contracts for draft assets. This in theory could see Trouba heading to Calgary for Huberdeau in exchange for the winger and retaining 50% of his contract.
While he has had some controversial moments with some of his hits being considered dirty, he set the tone, and brings physicality and the Flames are missing his style of play, since Mark Giordano's exit.
While the Flames have some good pieces in Kuzmenko, Mantha and Sharangovich, Conroy moving on from Huberdeau would be a commitment to the rebuild and saving the team money.
