I feel like the underperformance thing is overlooked in Calgary's favour.
Almost every player (exceptions being AM88, DR33 and MT19) had off years.
IF the team can capture some of the 2018-19 season offensive magic prior to the all-star break along with a better defensive corps due to the additions of Gus and Forbort then they can be a legit cup threat.
Not to mention Ritter came out the gate flying and slowed down later. Based on his interviews he sounds like he's confident again and the minor injury he had is history.
Don't count out the Flames - they definitely have the tools if they can find the confidence again
Worst case they get blown out and the team gets overhauled which they likely need if they underperform again.
