The predecessor of NCAA is American College Basketball League. 1939, the National Coach Committee held a league match, in which five college teams participated. Since then, NCAA has taken over sponsorship and become the most influential basketball league in the United States, even after the establishment of NBA 1946. NCAA generally refers to the competition in which more than 300 powerful universities participate, which is equivalent to the first-class university alliance. The conditions for attending NCAA University are very strict. First, there are at least four sports and sports teams for men and women in universities. Secondly, the players' SAT and ACT scores must be above 2.0 (Garnett was forced to participate in the draft because he failed to meet the minimum requirements).

Since the 1990s, the teams that entered the NCAA semi-finals mainly included the University of Maryland (champion in 2002), Duke University (champion in 199 1 year, champion in 1992 and champion in 5438+0 in 2006) and University of Kentucky (199)

Competition system: NCAA participating universities are almost all over the United States, and the participating teams are generally divided into leagues according to regions. A league has a dozen or dozens of teams, a host and a regular game. At present, there are 3 1 leagues recognized by NCAA, and the first place in each league automatically obtains the qualification to enter the top 64 NCAA. The other 33 places are selected by experts according to their strength. The top 64 will be divided into the Eastern District, the Western District, the Central and Western District and the Southeast District for the single-game elimination of neutral cities, and the champions in each district will be the last four. The semi-finals and finals are usually held in one city, and the rule is still single elimination. On the day of the final, the NBA will not play any games to show respect.
