Rules
Needham Youth Basketball League is an instructional league designed to promote sportsmanship and appropriate competitiveness. Each coach’s goals are:
-
To realize an improvement in individual skill level and understanding of team play for ALL players
-
Ensure a positive experience for ALL players (not just those on one’s team).
The program strives to achieve parity throughout the league, both in team records and playing time. Coaches should be sensitive to the lessons of winning and losing that the players will experience, but the concern for winning and losing should come only after learning and fun have been achieved. Before reviewing the list of general rules of High School Basketball that apply, please read and understand the following league-specific exceptions and guidelines in the pages that follow.
Spirit of the League:
Following on the goals noted above, our league has many league-specific rules that are carefully crafted and intended to help players of all abilities to develop their skills in a fair and balanced approach.
While it is okay for coaches to note our league-specific rules during practices, the focus in practices should be basketball fundamentals.
During games, it’s important for coaches and referees to be aware that the players are generally not aware of the nuances of our league’s rules against double-teaming, zone defenses, isolation, etc.
It’s reasonable to expect that our league-specific rules are unintentionally violated during games. If league-specific rules are violated by a player:
-
A referee should try to encourage the player to stop the violation while the game keeps playing (e.g. shout "watch the double team", "watch the zone", etc.)
-
Any time a team gains an advantage unfairly, the opposing team should be awarded the ball.
-
If the player continues to violate a given rule, a ref should ask that player’s coaches to explain the rule to the player during the next break.
A ref should only call a technical foul on a specific player if it’s blatantly obvious that either:
-
the player is violating the rules purposefully/intentionally
-
the player’s behavior is unacceptable.
Teams and their coaches are expected to respect the goals of our league-specific rules and not strategize to take advantage of these rules (e.g. ‘game the system’).
If a team is found to be intentionally using strategies/techniques that aim to take advantage of the league-specific rules, that team’s coach(es) will be subject to immediate review and potential ejection from not only the game, but the entire program.
Violations might include strategies/techniques for players to intentionally double-team illegally, play zone (play ‘center field’ in the lane), stall excessively, isolate repeatedly, commit fouls repeatedly on specific players, wait to see an opponent’s line-up before sending your own team on the floor, etc.
Such strategies/techniques belie the league’s goals and violate the ‘Spirit of our League’, and they will not be tolerated.
Upon observing such violations, a ref should stop the game/clock and quietly review his/her observations with the team’s coach. If the pattern persists, a technical foul should be called with each additional violation.
Also, we are all setting an example for everyone involved, and the example being set should be positive. Thus, there is ZERO tolerance for any barking/chirping/complaining/etc. of any kind from any coaches, spectators, and players.
Any such violations and/or inappropriate misbehavior are subject to an immediate technical foul and/or ejection.
All technical fouls and/or potential violations of the ‘Spirit of the League’ should be reported to the league’s Director immediately for further review/action.
Coaches and Referees:
Game referees are assigned by the league’s Director.
During the regular season, an assigned ref that cannot cover a ref assignment has the responsibility of finding a replacement to fulfill his/her assignment.
During the post-season tournament, an assigned ref that can’t ref an assigned game must alert the league’s Director so an appropriate replacement can be identified.
Each referee should have his/her own whistle and arrive 10 minutes early, in their reffing shirt and dark pants.
Pre-Game
A scorekeeper is assigned to every game. Coaches should immediately fill out their players' names/numbers when they arrive at the gym for a game.
Coaches should have their line-ups made before they arrive at the gym. There are substitution grids under the resources tab on the website.
Post Game:
The winning coach of each game must report the score onto the app or website within 24 hours. If they are unable to do so, email the score to the league’s Director.
Any issues or concerns should be addressed with the league’s Director as they arise.
Game Time:
Start games on time! If you don’t keep games moving, later games will be affected.
Each game has four, 10-minute quarters. There are substitutions at the 5 min mark and in between quarters.
The clock should always have running time EXCEPT:
-
At the 5:00 mark of each quarter, stop the clock for substitutions (see ‘Substitutions’)
-
Timeouts: 3 per team per game, but no more than 2 per half (a team can’t carry 3 to the 2nd half)
-
A 1-minute break between quarters and a 3-minute break at halftime (unless running late)
-
All whistles during the last two minutes of a game or overtime
-
During free throws
-
Junior Girls League only: Hold the clock when a team has the ball in the back court during the last 30 seconds of the 4th quarter and OT. Start the clock when the ball is possessed in the offensive half-court
-
On injuries and/or at the referee’s discretion
Line up, Substitutions and Playing Time:
Five players are necessary to start a game. If a team does not have 5 players after a 5-minute grace period, that team forfeits the game. We want the players to play, so coaches can agree to play 4v4 or split teams up so the kids at least get an hour of exercise.
Coaches should be prepping their line-ups for the entire game BEFORE arriving at the gym, so make sure parents are giving you 24-48 hours advance notice of any expected absences.
There are controlled substitutions at the beginning of each quarter, at the 5:00 mark of each quarter, at the beginning of each overtime period, and at the half-way mark of each overtime period.
At each line-up change, referees should quickly line teams up so each player can identify their defensive assignment. Teams can opt not to mirror each other in their defensive assignments if desired.
At the 5:00 mark of each quarter (or the half-way mark of each overtime period) the clock should stop but play should continue until the next “dead ball” or “defensive rebound”.
The team that has possession of the ball when the referee stops play for the mid-quarter subs will retain possession after the substitution (the possession arrow should not be changed here).
To keep games moving, this substitution period is neither a time for coaching strategy nor a time of rest. Have your players ready to line up. If this time is abused, a warning should be issued and a technical foul may be assessed as appropriate.
If the stoppage at the 5:00 mark occurs in a foul shot situation, the ref will keep both teams on the floor and proceed with the free throws to determine who will get the ball when play resumes. If the defense gets the rebound of the last free throw, the referee should then stop play and administer substitutions. If the offense gets the rebound, keep the clock stopped at 5:00 and continue until a change of possession.
A player is disqualified on a player’s 6th foul or 2nd behavior-related technical foul of the game.
Playing time requirements: Generally, there should be equal playing time for all following the chart below (use the provided game grid to track both teams):
# of Players - # of 5-minute shifts for each player per game
10 players- 4 shifts each
9 players- 4 play 5 shifts, 5 play 4 shifts
8 players- 5 shifts each
7 players- 5 play 6 shifts, 2 play 5 shifts
6 players- 4 play 7 shifts, 2 play 6 shifts
5 players- 8 shifts each
No player should play 2 more or less shifts than any other player on a team.
Violation of this rule is subject to forfeit with the exception of the sub-bullets noted immediately below.
-
If a player arrives late or is expected to leave early, that player should play at least half of the full shifts that remain during the time they are present, and not play 2 more or less shifts than any other player on the team during the time the player is at the game.
-
If a team is comfortably in control of a game (e.g. up 20+ points in the 2nd half), coaches should disregard the ‘equal time’ rules and instead play their players that would benefit most from extra playing time. Better players should only be reinserted if the gap in score narrows significantly.
A player should not sit out more than 2 shifts in a row unless unable to participate (e.g. if injured).
Ideally, the scorekeeper tracks the line-ups for each shift to ensure rules are followed, but coaches are expected to adhere to the guidelines regardless.
Players that must come out of a game but then are able to return (due to injury or other reasons), use best efforts to balance time according to the above guidelines.
Overtime: shift counts reset to zero for all players with each new overtime period.
3 Point Shots:
3-pointers are allowed throughout the game in all divisions.
DEFENSE
1. Overall Defensive Guidance for the NYBL
-
This is a man-to-man league.
-
No zone defenses are permitted.
-
This aligns with our mission as a developmental league for players of all abilities.
-
To learn more about this, please see our FAQs.
-
It is important that Coaches and Players demonstrate good sportsmanship and adhere to the spirit of the league.
-
This specifically excludes exploiting technicalities of the rules for competitive advantage.
2. Man-to-Man Defense (All Divisions)
What Is Allowed
-
Each defender must be responsible for one offensive player.
-
Switching is allowed (e.g., on screens or picks).
-
Help defense is allowed in the lane when a teammate is beaten on the perimeter (but not before they are beaten)
-
A defender may give their assigned player a cushion of up to one body length (~5 feet) when:
-
The offensive player is outside the 3-point line and
-
Is not an immediate scoring threat.
-
What Is Not Allowed
-
Defending an area instead of a player (i.e. zone defense).
-
Sagging into the lane to stop drives without responsibility for a specific offensive player.
-
Being more than one body length (~5 feet) away from the payer you are guarding when they are inside the 3 point line
-
“Center-fielding,” camping in the lane, or guarding space while ignoring an assignment.
3. Double-Teaming Rules
-
Double-teaming is not allowed in the backcourt, except in the case of a temporary, natural double-team that occurs when the offense sets a pick to free one of their players
-
Double-teaming the ball-handler is allowed in the front court in these situations only:
-
When the double-teaming player is still within arm’s length of the person they are guarding (i.e. defending a pick-and-roll when two offensive players are next to each other and defenders are communicating if they will switch or not).
-
When a double team naturally occurs (e.g. when an offensive player drives into an area with multiple defenders guarding offensive players).
-
When a perimeter defender is beat by the player with the ball, teammates can provide help defense.
-
Help must be brief and must not turn into a sustained illegal double-team.
-
-
Only the player with the ball may be double-teamed, double-teaming off the ball is not allowed.
-
Triple-teams (or more) are not allowed.
4. Offensive Indifference
A defender may be more than one body length (~5 feet) away from the player they are guarding when their assigned offensive player:
-
Is clearly outside the play (e.g., near mid-court), and
-
Shows no intent to participate in the offense.
In an instance of offensive indifference, the defensive player should remain within one body length of the 3 point line aligned to their defensive assignment. The defensive player is not allowed to play a standing or rotating zone (including standing in the lane), nor are they allowed to be a free-roaming double-teamer. They are allowed to provide help defense to teammates when they are beaten on the perimeter.
Once the offensive player re-enters the play, the defender must immediately return to playing their man.
5. Backcourt & Press Rules
Boys (5th/6th and 7th/8th Grade Divisions) and Girls (7th/8th Grade Division Only)
Quarters 1–3:
-
No defense is allowed in the backcourt.
-
Defense begins only after the ball crosses mid-court.
-
The offense must advance the ball into the frontcourt within 10 seconds.
4th Quarter & Overtime:
-
Full-court defense is allowed for a team that is:
-
Tied or trailing by any amount
-
Leading by <10 points
-
A team may be pressing and extend their lead to 10 points, at which point they cannot press
-
If their lead drops below 10 points, they are able to press again
-
-
Double-teaming is not allowed in the backcourt:
-
Traps, zones, and similar defenses are not allowed
-
If a pressing player is assigned to the offensive player inbounding the ball, they must guard that player and cannot “sag” or otherwise play zone
-
As an example, if the offensive team has only the inbounder and one receiving player in the backcourt, the defense should only have two players in the backcourt, both playing within one body’s length of their defensive assignment
-
The only exception is in the case of a temporary, natural double-team that occurs when the offense sets a pick to free one of their player
-
Girls (5th/6th Grade Division Only)
Quarters 1–3:
-
No defense until the ball crosses the 3-point line in the front court.
-
Defense must remain behind the 3-point line on offensive inbounds until the ball crosses it again.
-
Once crossed, normal front-court defense applies for that possession.
4th Quarter & Overtime:
-
No defense is allowed in the backcourt.
-
No defense until the ball crosses mid-court.
-
Once crossed, defense is allowed anywhere in the defensive half-court.
6. Enforcement by Officials
-
For violations of the defensive rules with respect to playing zone or double-teaming, referees will:
-
Stop play, restate the rule, issue a warning to the offending team, and award the ball to the offensive team
-
On a team’s second violation of the backcourt defense rules, issue a technical foul against the offending team, and award the offensive team one free throw and possession of the ball
-
-
Official Discretion:
-
Officials are empowered to enforce both the letter and spirit of these rules.
-
If an illegal defense results in an advantage, the officials should reverse the outcomes of that advantage when possible.
-
Officials may use their judgement if a player is unintentionally breaking the rules and a warning is more appropriate than issuing a technical foul.
-
Held Balls and Possession Arrow:
A jump ball will be held at the start of the game and at the start of each overtime period.
At each ‘held ball’ and at the beginning of the 2nd, 3rd , and 4th periods, award possession to a team on an alternating basis (e.g. the basic ‘possession arrow’ concept; refs should track by looking at the team benches and alternating placement of a coin or other object in a left or right pocket).
Refs should use discretion, but be quick to blow the whistle on a held ball for safety reasons.
Traveling and Double Dribble:
Call these violations consistently, as the players need to learn.
The only reason to use discretion is if the traveling is due to floor conditions or in the case of a novice player (see below ‘Other Rules & Guidelines’)
Picks/Screens:
Teach your teams to set proper picks that are stationary, with arms and elbows in a safe position.
Referees should call fouls on moving picks, or picks where arms/elbows are positioned incorrectly.
A player setting a pick can ‘cross their heart’ for protection (arms crossed like an ‘X’, hands firmly placed on their own shoulders), but again, elbows must not be raised.
A foul for a moving pick should NOT be called UNLESS there is contact made with a defender.
Other Fouls and Free Throws:
Basically, it’s a foul if a player gains an advantage (no matter how slight) by initiating physical contact on an opponent - - MAKE THE CALL!! The players need to learn.
Free Throws
- Foul shots should be taken from the standard free throw line.
- Lane violations
- Boys (5th/6th and 7th/8th Grade Divisions) and Girls (7th/8th Grade Division Only): Call a violation if the shooter steps over the line on the shot
- Girls (5th/6th Grade Division Only): shooters are allowed to go over the line without it being a lane violation
- All Divisions: Call a lane violation on the first player whose foot touches the floor in the lane too early; if the violation is on defensive team and the shooter makes the shot, don’t call the violation and the shot counts.
On the last free throw by a player per trip to the line, players may move from their respective places upon the ball’s release by the shooter.
All technical fouls result in 2 shots for the opposing team plus possession (2 technical fouls against any one person, if behavior-related, is grounds for an immediate ejection).
Bonus:
On the 7th-9th team foul of either half: the opposing team shoots ‘1 & 1’ (the shooter is awarded a second free throw if first is made; each missed shot is a live ball).
On the 10th (and any subsequent) team fouls of either half, the opposing team shoots 2 free throws (the 2nd shot is live if missed).
Overtime:
If tied at end of regulation time, a 5-minute overtime should be played.
Use a jump ball to start OT
Each OT will have 2 shifts of 2:30 each (stop the clock at 2:30, and wait for the next stoppage in play).
Equal playing time starts fresh with each OT period that has multiple shifts (all players are at zero time).
Each team gets one timeout per overtime period.
Running time for the first three minutes (except free throws); stopped time on whistles in the last two minutes.
4th quarter defense rules apply (see GENERAL DEFENSE above).
With less than 30 seconds remaining, the clock should be stopped while the ball is in the back-court. The clock should start once the ball is touched by the offensive team in the offensive half-court (the rule to cross the mid-court line within 10 seconds still applies; if a game’s outcome is not in doubt, the clock can run).
Use as many OT periods as needed, BUT be conscious of the schedule. If a game is running excessively long, shave the period to 2 or 3 minutes with no shift change.
If multiple one-shift OT periods are played, no player should sit for more than one OT period at a time (unless a team has more than 10 players).
Attitude:
Referees should not tolerate ANY complaining from coaches or players during the game (zero tolerance - - this league emphasizes sportsmanship, and coaches are setting examples for the players).
Referees should stop play, and give the player or coach an IMMEDIATE warning (record it in the book, and alert your league’s Director after the game).
If complaints persist, the ref should call a technical foul (2-shots and the ball), and again for any subsequent violations (it’s their fault, not yours - - MAKE THE CALL!).
Coaches needing clarification with referees can discuss quietly/discreetly during breaks, but coaches should know the rules before doing so.
Other Rules and Guidelines:
Remember, this is a developmental/instructional league: while calls relating to infractions above should be made, use discretion (especially early in the season) on a player that is clearly struggling with a rule (i.e. traveling or double-dribble - - blow the whistle, teach, and positively encourage the player(s), etc.). That said, tolerance for violations should be lessened as the season progresses and then eliminated altogether for the year-end playoff tournament. See ‘Spirit of the League’ above for an approach.
Be authoritative and audible when making your call as a referee. Make sure both teams and the scorer’s table hear who committed a foul by identifying team and number clearly and audibly.
