A quick google search showed me the only deal the Flames have retained salary on was David Rittich in 2021.
I believe the hold up here is not necessarily the Flames willingness to retain (IMO really unlikely) but the other teams willingness to pay the required price for them to do so.
All of the rumoured players to be traded are on quite favourable deals right now, so I, for one, completely understand Conroy "sticking to his guns" and hope he continues to do so.
Each players next deal is the rights holders problem, with Markstrom the farthest out. I am expecting excellent returns on all even without retaining salary.
