 In the 2010s, some football-specific stadiums (either enclosed domes like the Georgia Dome or open-air Bank of America Stadium) have been or may be replaced by multipurpose stadiums with a retractable roof (such as Mercedes-Benz Stadium) where NFL football remains the primary tenant but which can also accommodate soccer, concerts, major conventions, and NCAA Final Four basketball, although not baseball as that demands radically different field dimensions.While multipurpose stadiums were intended to easily accommodate both American football and baseball (and in some cases, association football), the fundamentally different sizes and shapes of the playing fields made them inadequate for either sport.When used for baseball, the lower-level boxes were usually set back much farther from the field than comparable seats in baseball-only parks because they swiveled into position for American football and association football.
