And then there were 1s. With wins by Houston and Auburn on Sunday, the Final Four will have all four No. 1 seeds for the second time in NCAA Tournament history. The only other time since seeding began in 1979 was in 2008, when Kansas, Memphis, UCLA and North Carolina went to the Final Four, in San Antonio, no less. This year also marks the first time higher seeds went 12-0 in the Sweet 16 and Elite Eight, capping a year of chalk that ends on the Riverwalk. Auburn will face Florida in an all-SEC national semifinal in San Antonio, with Duke playing Houston in the other.
