Best quote from Beyond the Whistle: Mastering Basketball Fouls and Violations
Every foul is a violation, but not every violation is a foul. It’s all about whether there’s illegal contact or just a procedural mistake.

Basketball rules and fouls (names and types)
Frequently Asked Questions
The cylinder principle is a rule used to define the personal space a player "owns" on the court. Imagine an invisible tube extending from the floor to the ceiling around each player; for a defender, this space is bounded by their palms in front, their buttocks in the back, and the outer edges of their arms and legs on the sides. As long as a player stays within this verticality, contact initiated by an opponent is generally not their fault. However, if a player reaches out of this cylinder—such as by extending a hip or arm into an "abnormal" position—and causes contact, a personal foul is called.
The distinction depends on whether the defender has established a "legal guarding position" before contact occurs. To draw a charge, a defender must be facing their opponent with both feet planted on the floor before the collision. If the defender is still moving toward the offensive player or hasn't set their feet, the official will call a blocking foul. While defenders are allowed to move laterally or backward to maintain their position, they cannot move toward the ball handler to initiate the hit. Additionally, defenders usually cannot draw a charge if they have a foot inside the "no-charge semi-circle" under the basket.
In the NBA, technical fouls are behavioral, non-contact fouls that are tracked separately from personal fouls; a player can have five personal fouls and one technical and remain in the game. In contrast, under FIBA rules, a technical foul actually counts toward a player’s five-foul limit. Both leagues agree that two technical fouls for unsportsmanlike conduct result in an automatic ejection. Furthermore, the penalty for a technical foul is a single free throw, which in the NBA can be taken by any player on the court, while in FIBA, the head coach designates the shooter.
The defensive three-second rule prohibits a defender from standing in the "paint" (the restricted area) for more than three consecutive seconds unless they are actively guarding an opponent within arm's reach. This rule is strictly enforced in the NBA to keep the lane open for drives and dunks. However, this rule does not exist in FIBA play. In international games, defenders are legally allowed to "park" in the paint for the entire possession, which often results in a more cluttered interior compared to NBA games.
In the NBA, players are prohibited from touching the ball while it is in the imaginary cylinder above the hoop, even after it has touched the rim. In FIBA (international) rules, the ball becomes "fair game" the moment it touches the metal of the rim. Once it hits the rim, any player can legally swat the ball away or tap it into the basket, a distinction that often requires NBA players to adjust their instincts during international tournaments like the World Cup.
