The history of how the Truman Sports Complex came to be is pretty fun to read: https://www.jchs.org/jchs-e-journal/2024/8/8/its-future-uncertain-its-past-a-blastAs a life long Chiefs and Royals fan I HATE them leaving that area. But the city had 50 years to figure out how to make that area some type of destination place. Instead they did Jack ____. Actually they did less than that. It's like they gave up 20-25 years ago.
I can't find them right now, but there were some pretty cool plans for development of that area after the stadiums were built. It never really materialized as there are three cities who all have land out in that area, and it made it extremely complicated.
Edit: Here is the blog I was looking for talking about how complicated developing the area was: https://open.substack.com/pub/eileennormileweir/p/major-league?r=1mxipp&utm_medium=ios
