 With the completion of the Truman Sports Complex in Kansas City in 1973, a model for purpose-built stadiums was laid down.Since Oriole Park at Camden Yards opened in 1992, most major league sports stadiums have been built specifically for one sport.From the late 2000s onward, however, some football specific stadiums that are either domed or open-air (Texas Stadium, RCA Dome, Georgia Dome, and Bank of America Stadium) have been or may be replaced by multipurpose stadiums with a retractable roof (Cowboys Stadium, Lucas Oil Stadium, and Mercedes-Benz Stadium) and even a roll-in natural grass field (State Farm Stadium) where NFL football remains the primary tenant but which can also accommodate other events year-round (soccer, concerts, major conventions, and NCAA Final Four basketball), although not baseball as that demands radically different field dimensions.
