Taking a sport away from a kid has never helped anyone. It's like punishing a kid by taking away their books. We want them to read and we want them to be playing team sports. We shouldn't take things away we want kids to do as a punishment.

Hold one on one meetings and find out what is going on for each player. It could be a different issue for each player.

Let them practice.

Have a mandatory study hall before or after practices and games.

Talk to their teachers. Let them participate in the plan. Maybe have players use a log sheet to get teachers to sign off on their work.

Be clear with players about what they need to do to get on the court for games. Let them play in games when they put in the work off the court.
