College basketball's March Madness will be played in largely empty arenas in an effort to slow the coronavirus pandemic, the NCAA announced Wednesday, a move that threatens to drain the signature school spirit from one of the biggest events on the sports calendar. NCAA President Mark Emmert said only essential staff and limited family will be allowed to attend the men's and women's tournaments, which begin next week. The NBA game between the Warriors and Nets in San Francisco on Thursday night will also be played without fans, and the Mariners said they will move their games out of Seattle for all of March because of the COVID-19 outbreak.
