So are you planning on quitting on the team mid-season? I would finish out the season and move him next year. I would never let my kids quit a team during the season. If you are not looking for the refund then just play both.
If it is that bad you want to leave mid season then be an adult and talk to the coach. I would make sure this is what your kid wants to because it’s all about them not us. Coaching is not easy when it’s you as the coach but from the stands every is an expert
