<blockquote>A few years ago, to maintain the stadium’s top-tier status, the Rams sought an estimated $700 million of improvements. St. Louis balked, and the Rams started looking elsewhere.

To cover costs, the city paid about $6 million for annual debt service and maintenance for the stadium but collected only about $4.2 million in direct revenues from Rams games, according to the Mayor's office.

The county paid $6 million annually; it's unclear how much of that was offset by Rams-related revenues.
