question:
Passage: The first NCAA Tournament was organized by the National Association of Basketball Coaches. Oregon won the inaugural tournament, defeating Ohio State 4633 in the first championship game. Before the 1941 tournament, control of the event was given to the NCAA. In the early years of the tournament, it was considered less important than the National Invitation Tournament (NIT), a New York City-based event. Teams were able to compete in both events in the same year, and three of those that did soUtah in 1944, Kentucky in 1949, and City College of New York (CCNY) in 1950won the NCAA Tournament. The 194950 CCNY team won both tournaments (defeating Bradley in both finals), and is the only college basketball team to accomplish this feat. By the mid-1950s, the NCAA Tournament became the more prestigious of the two events, and in 1971 the NCAA barred universities from playing in other tournaments, such as the NIT, if they were invited to the NCAA Tournament. The 2013 championship won by Louisville was the first men's basketball national title to ever be vacated by the NCAA after the school and its coach at the time, Rick Pitino, were implicated in a 2015 sex scandal involving recruits.
