The Calgary Flames had a difficult bench to manage last season.
Glen Gulutzan was lucky to find and leverage the now famous 3M line with Mikael Backlund, Michael Frolik, and Matthew Tkachuk. That trio actually became one of the best hard minutes combinations in the league. Gulutzan was also able to lean on the Mark Giordano and Dougie Hamilton pairing to handle tough matchups at even strength.
After those guys, though, things got dicey in a hurry. Because of certain limitations and liabilities scattered throughout the rest of the roster, the Flames were often exposed by teams with quality depth or by opposing coaches on the road.
