Sixteen teams are left in the NCAA Men’s Basketball Tournament and these four venues play host as the field is narrowed to four. Two 20,000-seat pro arenas – one Midwest-honest, the other LA-glitz and glamour, and two oversized football stadiums – one University-owned and regularly converted to basketball and the other a big ol’ Southern football mansion, definitely not suited for basketball. This is the big time, with lots of fans, media and businesses wanting in, so sometimes the buildings are oversized and not quite right. The games, however, are set to impress.
