NBBL Rules 2017
NBBL play is governed by international FIBA rules. Listed below are some specific
NBBL playing rules which are exceptions to those international rules. If you have any questions during the season, please contact a division coordinator or the league commissioner for clarification.
1. Length of Games
Games in all divisions shall consist of four (4) playing periods or quarters. A 1 minute break will be given between quarters and an 5 minute half-time break.
● For Divisions B1/G1 (boys and girls, grades 1-2), B2/G2 (boys and girls, grades 3-4 and B3/G3 (boys and girls grade 5-6) game duration is 32 minutes (8-minute quarters).
● For Divisions B4/G4(boys and girls grade 7-8) and B5 (boys grades 9-12) game duration is 40 minutes (10-minute quarters).
Games are played with a running clock. During play, the clock will only stop during foul shots, time-outs, injuries and the last 2 minutes of each half (2nd quarter and 4th quarter).
No games shall end in a tie. In the event of a tie at the end of regulation play, a 1- minute time-out will occur. The teams will then play a 4-minute overtime period. The 4 minute OT applies to all divisions. A jump ball will start the overtime period. Each team will be given (1) time-out during the overtime period. During the overtime period, the backcourt defense rules for the last substitution period of the 4th period will apply throughout the overtime. This procedure will be repeated until there is a winner.
Substitutions are to occur at approximately the 4 minute mark of each period in Div. 1 (Gr. 1-2), Div. 2 (Gr. 3- 4) and Div 3 (Gr 5-6) games, and at the 5-minute mark in Div. 4 (Gr.7-8) and Div. 5 (Gr. 9-12) games. This time-out is to take a maximum of one (1) minute. The substitution time-out is not for the coach to have a strategy session with the players. The coach should have lineups prepared in advance and have substitutes ready to enter the game.
For all regular season games, for teams of less than ten players, each player must play at least one-half of the game (4 substitution periods). For teams often players or more, each player must play at least 3 substitution periods.
However, if a player arrives after the scheduled game time, is injured, or acts in a disrespectful or inappropriate manner, the coach has the discretion to play that player for less than the required time. Additionally, each player must sit (not
play) for at least one substitution period (4 minutes in Div. 1 (Gr. 1- 2), Div. 2 (Gr. 3-4) and Div. 3 (Gr 5-6), and 5 minutes in Div. 4 (Gr. 7-8) and Div. 5 (Gr.9-12), unless no substitutes are available to play. It is strongly recommended that all players play the same amount of substitution periods.
For all playoff games, the minimum playing time for each player will be reduced to 3 of the 8 substitution periods.
Referees are to instruct the scorekeeper to hold up their arm at the 3:45 minute mark of the quarter for Div. 1 (Gr. 1-2), Div. 2 (Gr. 3-4) and Div. 3 (Gr 5-6), or the 4:45 minute mark for Div. 4 (Gr. 7-8) and Div. 5 (Gr. 9-12) as notification that the mid-point of the quarter is approaching. The referees, at their discretion, shall then call a substitution time-out. The game should not be
stopped for substitutions during a scoring opportunity. Referees should only stop play at an appropriate time i.e. after a basket is made, the ball goes out- of- bounds, a violation, or when the ball is in the neutral zone around mid-court.
Possession of the ball is retained by the team in possession at the time of the time-out. If a coach takes more than one minute to substitute, the referee should give a delay-of-game warning. If the coach continues to delay after the warning, the referee shall charge a technical foul for delay of game.
4. Back Court Defense
Backcourt defense is not allowed at any time for the Boys and Girls Div. 1 (Gr. 1-2) and Boys and Girls Div. 2 (Gr 3-4). Once the defending team has gained possession of the ball, the offensive team must go back across the mid-court line and wait to pick up their opponent on defense. Backcourt defense is only allowed during the last 4 minutes of each half in Boys and Girls Div. 3 (Gr. 5-6) and the last 5 minutes of each half in Boys and Girls Div.4 (Gr. 7-8). Backcourt defense is allowed at anytime in Boys Div. 5 (Gr. 9-12).
5. 3-Point Shot
The 3-point rule does not apply for the Boys and Girls Div. 1 and 2 (Gr 1-2 and Gr. 3-4).
6. Basket Height and Balls
The baskets for Boys and Girls Div. 1 (Gr. 1-2) and Boys and Girls Div. 2 (Grade 3-4) will be at 8 feet. All other divisions will be at 10 feet. Boys Div. 1 (Gr. 1-2), Div. 2 (Gr. 3-4) will play with size 5 ball. Boys Div. 3 (Gr 5-6) and all Girls Divisions will play with a Size 6 ball. All other Boys Divisions will play with a Size 7
7. Free Throw Distance
In the Boys and Girls Div. 1 (Gr. 1-2) and Boys & Girls Div. 2 (Gr 3-4) free throws will be taken from the mark of the circle in front of the free throw line. In all other divisions, the standard free throw distance will apply.
8. Man-to-Man Defense & Zone Defense
For Boys and Girls Div. 1 (Gr. 1-2), Div. 2 (Gr. 3-4), Div. 3 (Gr 5-6) players are required to play man-to-man defense. Zone defenses are not allowed at anytime during the game. Zone defense or a combination of defenses is only permitted in Boys and Girls Div. 4 (Gr. 7- 8), and Boys Div. 5 (Gr. 9-12).
In addition, in Boys and Girls Div. 1 (Gr 1-2) and Boys and Girls Div. 2 (Gr 3-4), the defense is not permitted to steal the ball from an offensive player if that offensive player has control of the ball.
Each team will be allowed (3) one-minute time-outs per game. The time-out can be only be called by the coach during a dead ball or while in possession of the ball. No player substitution is allowed during the time-out. Each team will be granted (1) one-minute time out per 4-minute overtime session. Unused timeouts from the regulation time period of the game DO NOT carry over to the
Scorekeepers will keep track of all fouls charged against each player. A player will have “fouled out” after being charged a fifth foul and shall not be allowed to play for the remainder of the game. Each team is allowed 7 team fouls per half before the bonus goes into effect. Two bonus foul shots will be awarded beginning with the 8th team foul and all ensuing fouls of the half. In an overtime period, the team fouls from the 2nd half carry over to the overtime period.
In no case shall the coaches or players be allowed to argue judgment calls such as fouls, out-of-bounds calls, or other violations. Arguing with the referee will result in an automatic technical foul regardless of the justification. Any disagreement
on rules interpretation should be brought to the attention of the Division Coordinator or League Commissioner.
11. Intentional Fouls
On a fast break, should the referee determine that a pushing foul is intentional and with excessive force, the referee will call a technical foul and the offending player must be ejected from play for the remainder of the game.
12. General Enforcement of the Rules
The Referees are to use their discretion in applying the rules between the divisions. Referees will enforce all rules for players in the upper divisions (Div. 4 & 5). For the younger divisions, (Div. 1, 2 & 3), the referees are to be less strict in calling violations initially since some of these players are still learning the game. For example, the referee should use discretion in strictly enforcing the 3-
second rule. The player may first receive a warning that he/she is in the lane for more than 3 seconds. The referee and the coach should also take a moment to ensure that the player understands what they mean by being “in the lane”. If the
player continues to make no attempt at leaving the lane area, then the referee should call 3 seconds. The referees are asked to enforce the rules in a consistent manner between teams, keep players from hurting each other and also to ensure consistent enforcement of the rules considering the age of the players involved.
Please remember that this is a recreational, instructional league for the enjoyment and benefit of our children.
Zero Tolerance Policy
Fighting, use of profanity, or other inappropriate behavior or gesture by any player, parent, coach or spectator will absolutely not be tolerated, and will result in immediate removal from the game. The offending party will be asked to leave the premises, and with a 2nd occurrence, expulsion from all participation in the league for the remainder of the year.
Bench Area is “Players Only” Area
The bench area is reserved for players and coaches, scorekeepers and timekeepers only. Spectators and parents are not allowed to enter the bench area to avoid distracting coaches, scorekeepers and timekeepers. Seating is provided in the gyms
directly opposite the player benches. Coaches are requested to strictly enforce this rule.
