Oklahoma State basketball: View the March Madness bracket and schedule for 2021. Oklahoma State will meet Liberty in the opening round of the NCAA Division I Men's Basketball Tournament in 2021. The game will be played on March 17th in New York City. March Madness is the name given to the series of events held each year in the United States that include: the NCAA Men's Division I Basketball Championship, the National Women's Division I Basketball Championship, and the National Collegiate Athletic Association (NCAA) Division II and III Championships. The term "March Madness" was first used by American broadcaster Ned Rountree to describe the NCAA Division I Men's Basketball Tournament in 1953. The phrase became popular after an audience of millions watched Kentucky beat Kansas in the championship game of that year's tournament. Today, "March Madness" is used to describe the entire month-long period beginning with the start of the college basketball season in November and ending with its conclusion in April. Kentucky's Adolph Rupp is considered the father of modern March Madness. Before Rupp's arrival at UK in 1937, there were no commercial television contracts, so coaches had little incentive to win games early in the season. Once Rupp took over, he implemented a strategy that would come to be known as "Rupp's Runts".
