A quad 1 win in college basketball refers to a victory against an opponent that is ranked highly in the NCAA Evaluation Tool (NET). In order for a game to be considered a quad 1 win, it must meet certain criteria based on the NET rankings, such as playing the game at home and the opponent having a NET ranking of 1-30 for home games, 1-50 for neutral-site games, and 1-75 for away games. These wins carry significant weight in the selection process for the NCAA tournament, as they indicate a team’s ability to compete with top-level opponents.
