Take a look back at some of the rules changes that have taken place over the years.
(Changes/clarifications implemented prior to season, except where noted)

Initial Rules
• 60-game schedule followed by championship playoffs involving the top three teams in each division.
• Games are 48 minutes long.
• Players are allowed six personal fouls.
• Every time you scored, the other team is given possession of the ball.
• Zone defenses are allowed.

1946-47
• Zone defenses outlawed on January 11, 1947.

1947-48
• Player fouls allowed per game increased from five to six.
• Maximum roster size reduced from 12 to 10 players per team.

1950-51
• After a free throw is made in the last three minutes, there is a jump ball (between the player who committed the foul and the player fouled) instead of possession for the team that committed the foul.
To eliminate deliberate fouling and roughness

1951-52
• Lane widened from six to 12 feet
Change primarily attributed to the dominance of George Mikan

1952-53
• The late-game free-throw rule (see 1950-51) now required the jump ball to take place between the man who is fouled and the player who is guarding him.
To eliminate the advantages of having a tall-man foul a short-man.

1953-54
• Players limited to two fouls per quarter and if a third foul is committed; the player has to sit out the remainder of that quarter.
The rule is rescinded when it fails to prevent late game fouling.

1954-55
• The 24-second shot clock is introduced.
• A penalty free throw is awarded following a team’s sixth foul in any quarter.
Both rules had to be adopted to make each one work. The time limit made in unnecessary for the trailing team to foul deliberately, since it would get the ball after 24 seconds. The foul limit made it too costly to foul to prevent a chance at a basket.
• The penalty for a backcourt foul became two shots – three to make two if you are over the limit.
• Offensive fouls are treated as violations, no free throws and the defensive team gets possession. The foul would still count towards a player’s limit of six personal fouls.

1964-65
• Lane widened from 12 to 16 feet
Change primarily attributed to the dominance of Wilt Chamberlain

1966-67
• The team foul limit is reduced to five per quarter. In the last two minutes of any period, a team is allowed only one foul before the penalty, even if it hadn’t used up its allotment.
• The following language was added to the Zone Defense Rule: "After the offensive team has advanced the ball to its front court, a defensive player may not station himself in the key area longer than three seconds if it is apparent he is making no effort to play an opponent. The three second count starts when the offensive team is in clear control in the front court."

1972-73
• No foul shots are attempted, other than shooting fouls, until the fifth team foul of any period.
• Other than the shooter, players are no longer restricted from entering the lane on free throws attempts.

1974-75
• Fine increased from $50 to $100 for a player or coach ejected after being charged with a technical foul for unsportsmanlike conduct.
• A timeout request made at the instant time expires for a period shall not be granted and the period ends.
• In the last two minutes of the game or overtime, no timeouts are allowed once the ball is inbounded until the ball is in the frontcourt.
• The “force out” rule is clarified as incidental contact near a boundary line, which causes a player to commit a violation or go out of bounds, and neither team is responsible for the action. The offensive team retains possession.
• When there are punching fouls on both teams during the same play, the team last offended is awarded possession.

1975-76
• After any playing court violation, the ball is to be put into play at the sideline.

1976-77
• Excessive and/or vigorous swinging of the elbows, without contact, is a violation.
• If a defensive player causes the ball to go out-of-bounds, the offensive team, on regaining the ball for throw-in, shall now have the unexpired time or 5 seconds (instead of 10), whichever is longer, to attempt a shot.
• For an inbounds play for the last two minutes, the offensive team has the option of moving the ball to midcourt or taking it at the spot following a timeout.
• The “force out” rule is eliminated.
• If less than five seconds appear on the 24-second clock when the offensive team is entitled to a throw-in, the clock will be reset to five seconds.
• The team that gains possession after the opening tap will put the ball into play at their opponent’s end line to begin the fourth period. The team losing the opening tap will put the ball into play at their opponent’s end line at the beginning of the second and third quarters.
In putting the ball into play, the thrower-in may run along the end line or pass it to a teammate who is also out-of-bounds at the end line--as after a score.
• Any player who engages in a fight is subject to a fine of $10,000 and a suspension.
This went into effect March 7, 1977.

1977-78
• If a coach wants to discuss a rule or an interpretation of a rule prior to the start of a period, it will be mandatory for the officials to ask the other coach to be present during the discussion. Previously, the rule only addressed pre-game discussions.
• Any field goal that, in the opinion of the officials is intentionally scored in the wrong basket shall be disallowed.
• The 24-second shot clock shall be reset to 24 seconds on all violations, as well as after a zone warning.
• If the ball enters the basket from below, a violation has occurred.

• If a player is fouled and is subsequently ejected from the game before shooting the free throw(s), he must immediately leave the court and one of his teammates on the floor will be designated by the opposing coach to shoot.

1978-79
• Number of referees officiating game increased from two to three.
• Rolling the ball on the floor from out of bounds now allowed; penalty of loss of possession eliminated.
• Technical foul imposed on team instead of warning for first illegal defense and two technical fouls imposed for second and all subsequent violations. Illegal defense rules modified.
• Clarification added instructing players and coaches to proceed directly to dressing rooms, without pause or delay, following halftime. Previous rule only stated at conclusion of game.
• Clarification added to prohibit hand-checking through “rigid enforcement” of rule allowing a defensive player to retain contact with his opponent so long as he does not impede his opponent’s progress.
• The three-point field goal is tried in pre-season.

• If two offensive players on the weak side are positioned above the top-of-the-circle extended, one of the two defenders may occupy any area on the weak side, except that he may not enter the inside lane other than to: aggressively double-team the ball, or defend an offensive player(s) who is open because of a double-team on the ball, or as a normal reaction to a “ball fake.” Following a “ball fake,” the defender must immediately return to a legal position or double-team on the ball.

If neither team has taken a timeout in all four periods when there is 5:59 remaining, there will be a mandatory timeout after the first dead ball. Previously, timeouts were taken after dead balls after 9:59 in the second and fourth periods and after 6:59 in every period.
• If the offense retains possession after a jump ball, the clock is reset to 14 seconds or remains the same if there are more than 14 seconds on the clock. If the defense gains possession, the clock is reset to 24 seconds.
Previously, if the offense retained possession, the clock was reset to 24 seconds.)

• Brief contact initiated by a defensive player will be allowed if it does not impede the progress of the player with the ball.

2002-03
• Use of instant replay to review certain last-second plays at the end of each quarter and overtime periods. Replays will be conducted and processed in two minutes or less by the game officials. Replays are triggered automatically – and not at the discretion of the officials or teams.
• Instant replay will also be used when: (1) A foul for which the resulting free throws could affect the outcome of the game is called with no time remaining on the clock (0:00) at the end of the fourth quarter or any overtime period or (2) A foul is called with no time remaining on the clock (0:00) at the end of the first, second and third quarters.
In these situations, officials will review instant replay to determine only whether the called foul occurred prior to the expiration of time on the game clock and not whether the call itself was correct.

2003-04
• For a 20-Second Timeout, the official shall instruct the timer to record the 20 seconds and to inform him when the time has expired.

• Players not occupying a lane space during a free- attempt must remain behind the three-point line and above the free-throw line extended until the ball is released by the free-throw shooter.
• If a flagrant foul/penalty 1 is called and the fouled player is unable due to injury to shoot his free-throws, his team’s coach (not the opposing team’s coach) selects a replacement free-throw shooter from among players on the floor (not players on the bench) at the time of the foul, and the injured player is not permitted to return to the game.
• Note: The rules for unsportsmanlike acts (elbow and punching fouls) and flagrant fouls/penalty 2 state the fouled player’s coach selects the replacement free-throw shooter from any eligible player on his team (whether on the playing floor or the bench) and the injured player is permitted to re-enter the game following the free-throw attempts. There is no change to this rule.

2007-08
1. Rule 2 Section IV. e - Block/Charge Clarification
If two officials differ on a block/charge foul involving the restricted area and/or lower defensive box, they will conference and share information in an attempt to make the correct call. If no resolution is reached it will be treated as a double foul (See rule 12B VI -f).

2006-2007: Section IV- Different Decisions By Officials
a. The crew chief shall have the authority to set aside or question decisions regarding
a rule interpretation made by either of the other officials.
b. If two officials give conflicting signals as to who caused the ball to go out-of-bounds,
they will conference and reconstruct the play in an attempt to make the correct call. If no resolution
is reached, a jump ball will be signaled between the two players involved at the nearest
circle. If the two players cannot be identified, the jump ball shall be administered at the
center circle between any two opponents in the game. If one official signals and another official
clearly knows the call is incorrect, they should conference and the calling official may
change the call on the information given. However, if both officials are adamant about their
ruling, a jump ball should be held similar to above.
c. In the event that a violation and foul occur at the same time, the foul will take precedence.

called for a non-unsportsmanlike technical foul. A coach is not permitted to cross the midcourt
line and violators will be assessed an unsportsmanlike technical foul immediately. All
assistants and trainers must remain on the bench. Coaches and trainers are not permitted to
go to the scorer's table, for any reason, except during a dead ball.


3. Rule 5 Section VII. a - Clarification on Full Timeouts in Last Two Minutes
If a team has two (2) or three (3) full timeouts remaining when the fourth period reaches the 2:00 mark, one (1) of the timeouts will be changed to a 20-second timeout and they will retain only one (1) full timeout.

    - Whether the Flagrant Foul/Penalty 2 was called correctly or whether it should be downgraded to a Flagrant Foul/Penalty 1 or a Personal Foul.
    - Whether any other players committed unsportsmanlike acts immediately prior to or immediately following the Flagrant Foul/Penalty 2.

    2006-2007: Section II-Reviewable Matters
    a. If an instant replay review is triggered as described in Section I-a (1) and (2) above,
    the officials would review the tape to determine only the following issues:
    (1) Whether time on the game clock expired before the ball left the shooter's hand.
    (2) If the shot was timely, whether the successful field goal was scored correctly as
    a two-point or three-point field goal.
    (3) If the shot was timely, whether the shooter committed a boundary line violation.
    For purposes of this review, the official would look only at the position of the
    shooter's feet at the moment they last touched the floor immediately prior to (or,
    if applicable, during) the release of the shot.
    (4) Whether the 24-second clock expired before the ball left the shooter's hand.
    (5) Whether an 8-second backcourt violation occurred before the ball left the shooter's
    hand.
