The Flames owner is known for being cheap and shutting down deals his GM makes because he hate's retainingWhich is weird. They have no significant signings and have a ton of cap space. Markstrom only has 2 years left anyway. That's not a long time to retain.
I guess it depends on how much the other team is asking for. If it's $1m, then that's fair. If it's 50%, I wouldn't do it either.
