current NCAA men's rules. In all three tournaments, the team foul limit was four per 10-minute block (either the virtual quarter in 2017 and 2019, or the actual quarter in 2018), identical to the NCAA women's limit for each quarter. Also in all three tournaments, two shots were awarded for all non-shooting defensive or loose-ball fouls upon the fifth team foul in a 10-minute block. This is also identical to the current NCAA women's rule. In 2017 and 2019, each overtime period was considered a separate period for accumulation of team fouls, as in the (W)NBA. The fourth team foul in an overtime period triggered the so-called "double bonus". In 2019 only, the (W)NBA rule regarding team fouls in the final 2 minutes of a quarter during regulation, or any overtime period, was adopted between 8:00 and 10:00 and 18:00 and 20:00 of each half, as well as the final 2 minutes of any overtime. The rules of the National Federation of State High School Associations (NFHS), which govern high school basketball in the United States, follow NCAA men's rules on this point for both boys' and girls' play. Even though the NFHS rules divide the game into quarters, the team foul count resets only at halftime. Summary References Rules of basketball
