NCAA introduces coach's challenges to improve men's basketball game flow

The NCAA is implementing major rule changes for the upcoming basketball season, including allowing coaches to challenge certain calls in both men's and women's games to improve game flow. Men's coaches can challenge out-of-bounds, basket interference, and restricted-area defender calls, while women's coaches can challenge out-of-bounds, backcourt, possession, and foul calls, with different penalty rules. Additional changes include new officiating emphasis on delay tactics, physicality, and fouls to the groin, as well as discussions about moving to quarters in men's basketball.
