Defenders may be called for a personal foul if they make illegal physical contact while attempting to prevent an opponent from scoring. Using an unlawful screen to impede the route of a defender is a personal foul for offensive players. A penalty is imposed when a player is fouled while attempting to shoot. The referee awards two free throws, and the fouled player is allowed to stay in the game. The only time a defensive player doesn't receive a foul is if he/she is guarding an opponent who has reached full-court pressure. In that case, the defensive player can stay with the player into whom he/she is defending the ball, but cannot leave his/her feet. A personal foul is worth five points for the opposing team. If you're up by four or more points at the end of three minutes, it's best not to commit any more flags than necessary. There are still about five minutes left in the game, so there's no need to worry about ruining your team's chance at a victory.
