You must be related to the McCaskeys.
I’ll confess that in my haste, I thought you were referring to something else. Having said that, the McCaskeys aren’t that much worse than most owners, especially the charter owners. They’re not as successful as the Rooneys, but have been overall much more successful than the Fords and Bidwells. The Hunt family also had a 4 1/2 decade stretch of mediocrity until they hired Andy Reid and he drafted Patrick Mahomes.
At one time the McCaskeys deserved a large share of the blame. But they’ve opened the purse strings and aren’t involved in day to operations anymore. There’s no reason to believe they are pulling any strings that matter. As long as they’ve hired the right GM and coach they will be fine.
Also, the run in the 80s, mid aughts, and 2018 was better than anything KC had experienced before Patrick Mahomes came along. So while most of it was bad, not all of it was bad. And when it was good, it was very very good.
