I look at different coaches around the league and I do think Calgary could benefit from a new coach.
But Colorado series absolutely broke them a few years ago. Calgary had a belief in themselves and a relentless forecheck. They felt they didn't have enough grit after and all the players spent that entire off season thinking about nothing else, and it ruined them.
Here's the problem i see, and i do have some knowledge direct from the players (i won't say who but any mod that wants to confirm via dm with me can).
The coaches treat different players differently. They let certain players off the hook (Gio) for things that they don't the other players. Flames have a reputation for hard partying too, and i know certain players got a talking to about and and others they let it go and that bothered the room.
You also see it on the ice, Ward's system is different for different players. That means you can't move players up and down the line up very easily, or adjust, and the expectations are different.
Sometimes this can work, putting players in a system they can play in. But the players have no buy in and they hate that the expectations aren't the same for everyone.
I think of Todd Mclellan with the Oilers, he had 1 system, and wanted his bottom 6 to all play like McDavid and they just couldn't. He kept trying to do the square peg round hole thing.
When Tippet came in he preached that every player without the puck has to play a certain way, but on the forecheck left it up to the talent on the ice.
I see Trotz have a similar system. The Islanders play really tight puck support and their goal is to force turnovers. Like when a player is forechecking by themselves against 2 D and everyone hangs back, i see them try to force the pass where they want it to go, not create a turnover right then and there, but probably on the next pass.
So i think the flames would benefit from a coach that expects the same from every player, but I know for that to even haver a hope to work Gio and Monahan will have to go, as they won't buy into any system that doesn't give them special treatment.
