In St. Louis, another lease was the undoing. The Edward Jones Dome was leased to the Rams under the condition that they would remain in the city so long as the stadium, by 2015, maintained a "First Tier Standard." That standard, according to the lease agreement, meant "that the Dome and each component thereof must be among the top 25% of all NFL football stadia and NFL football facilities, if such NFL football stadiums and facilities were to be rated or ranked according to the matter sought to be measured."
