Final Four moving up
The NCAA women’s basketball committee is backing a move to play the Final Four two days earlier, starting next season.
The Final Four would go to a Friday-Sunday format instead of the Sunday-Tuesday configuration in place since 2003.
The committee also decided that the top 16 seeds should host the first two rounds. The move would hopefully bolster attendance in the first two rounds, which has become stagnant over the past few years. Last season, the NCAA averaged 5,466 for all rounds — 17th since the tournament began in 1982.
