Each team will be allowed to carry as many players on its roster as it wants. However, a maximum of 12 individual awards will be available to each team at each meet. If a team has more than 12 players at a given meet, the head coach will be given all of the individual awards and be responsible for determining who receives them and who doesn't – additional ribbons can be ordered by the coach or association (the coach/association is responsible for the cost of extra ribbons, these can be ordered by contacting firstname.lastname@example.org). Teams with more than 12 players on their roster are encouraged to rotate the players they actually bring to each meet so that there aren't so many players on the bench, which will work to decrease the number of mass substitutions and shorten the overall length of games. Conversely, teams are expected to have sufficiently large rosters, or have access to players at a younger grade level who can be moved up when needed, so that one or two injuries or illnesses do not cause them to cancel attendance at a meet. This will not be considered a legitimate, non-weather related excuse within the meaning of Rule A-5.
Girls will not be allowed to play in League meets for boys. Likewise, boys are not allowed to play in League meets for girls.
All players must be from the same school district or same community, except where:
- A player attends a public school in another community under the state's open enrollment law, or a private school in his/her community of residence or another community, in which case the player in question will have the option of playing for either his/her school's team or playing for the community's team – but not both. An example: a player living in Mosinee, but attending school at Newman Catholic (Wausau), can play for Mosinee or Newman Catholic, not both. For purposes of this exception, home-schooled children can play either for the team from the school district in which they reside, or for the team associated with the school or community where they are allowed to play school sports or participate in other extracurricular activities, but not for both.
However, no player attending public school, and living and going to school in the same community, can play on two unaffiliated teams during the same season. Some examples: a 7th grader from the territory covered by Eau Claire North High School can play on that team's "Blue" team (or "A" team) one week and on its "Red" team (or "B" team) another week, and "up" on the 8th grade team another week – these teams are all "affiliated." But that same player cannot play on a different weekend for another Eau Claire team that is not associated with the 7th and 8th grade teams described above.
- If a player living in School District A applies, for the upcoming semester, to attend school in School District B (either because the player is in the process of moving or is open enrolling), or to attend a specific private school, once that player is accepted in writing at the second school (i.e., either School District B or the private school), that player has the option to play for either the community where he/she is currently living (School District A) or the team associated with the school to which he/she will be attending the next semester (School District B or the private school in question). Where an application process is required (i.e., open enrollment situation and private school application process), acceptance by the new school must be in writing – it's not sufficient that an application has been made or that the player's parents have been informed orally that their son/daughter "will" or "probably will" be admitted at some point in the future.
- Two neighboring or contiguous Wisconsin Division 4 or 5 (Minnesota A) communities – or one Wisconsin Division 3 (Minnesota AA) and one Wisconsin Division 4 or 5 (Minnesota A) community – can combine their players if both communities otherwise would not have enough players to field a team at that grade level. No Division 1 or 2 (Minnesota AAAA or AAA) community can field a team in the League with players from another community, nor can two Division 3 (Minnesota AA) communities put forward a combined team. Teams that decide to use this rule exception must notify the League that they are doing so and include both community names in the team name (e.g., Flambeau-Lake Holcombe). Where combining is allowed, all players from the grade and gender in question in both school districts must be given the opportunity to play on any combined team (it can't be only the best players from one or both communities, or a hand-picked team). That means sending a note home from school to every student of that gender in both communities (or some other effective form of written communication), so no one is precluded from participation.
- No teams from communities with two or more public high schools will be allowed to construct multiple district rosters. Communities with two or more public high schools cannot field teams that draw players from territory that covers more than one of those high schools. If one middle school feeds two different high schools, those players living in the territory covered by High School A can play for A's feeder team; likewise, those players living in the territory covered by High School B can play on B's feeder team. Also, the students attending that junior high school can play together as a team.
- Certain children of teachers who are paid to teach and be the head varsity basketball coach in a district in which they do not live. For example, in the case of a head varsity coach who lives in District A, but is paid to teach and be the head coach of District B's girls varsity basketball team, that coach's daughters (not sons) can play on a team representing either District A or B during the 2019-2020 season, but cannot play for both. The same is true of a boys varsity coach's son. The rationale for this rule exception is that the child in question will very likely play for their parent once they get to high school and should be allowed to play with their prospective high school teammates while younger.
Also, a middle school basketball coach, who lives in District A, but is paid by District B to teach in their schools and/or coach a middle school basketball team, will be allowed to have his/her son or daughter (as long as his/her son/daughter is the same gender and in the same grade as the grade the parent is coaching) play in Saturday League meets, in limited situations, for the team representing District B. For that to be allowed, all three of the following conditions must be met:
- The teacher/coach must receive "significant" compensation to coach this specific team, over and above their teacher's salary. Significant means "not nominal" (i.e., $25 per season would be "nominal"); it must be consistent with what is paid by neighboring districts to its paid teacher coaches.
- It must be a condition of this teacher/coach's agreement with the school district that he/she not only coaches the team in question at school-sponsored games, but also at Saturday League meets.
- The player in question is not playing "up" solely for the purpose of playing for his/her parent. In other words, a 5th or 6th grader living in District A cannot play on District B's 7th grade team coached by his/her parent, even if all the other conditions above are met.
The rationale for this latter middle school coach exception to the general rule against players from multiple districts playing on the same team, is to allow coaches who are contractually-obligated to coach another team of the same age as his/her son or daughter, the opportunity to spend quality time with his/her child on weekends.
The objective of this rule as detailed in the various bullets above, is to have League teams that are community-based, and not regional or metropolitan area all-star teams.
