I’d say most dysfunctional franchises stay dysfunctional.
I think most dysfunctional franchises fall into either of two categories.
Category 1 would be owners who treat the team as a for-profit business, and don’t value winning. They might win sporadically or stumble into good seasons or players, but don’t have a passion for winning. Bottom line overrides winning.
Category 2 would be franchises that were at one time owned by a passionate owner who died and passed it on to their children who passed it on to their children and eventually it lands with some family member who simply doesn’t care, or someone who isn’t at all qualified to run the team. Lots of times these generational ownership families end up becoming Category 1 owners.
There are probably owners as well that didn’t value winning until they stumbled into a championship or generational talent that helped them pull out of dysfunction.
