Definitely check to see if there's an existing team with space.

That should have been “free” agent

Moco rec teams are organized and coached by parents/volunteers — it may be the most fun for him if he can find a team to join w some friends or classmates. Maybe email the school listserv to see if there is an existing team he can join? Worst case he can register as a “few agent” and he will be assigned a team after the registration period closes.

Never too late to go out and have fun. Close friend didn't start playing until high school, and played D1 with a scholarship. MoCo should have received level signups available.

My son is pretty new to basketball but wants to play on a rec team. I see that there is a rec league for Montgomery County. We live in Bethesda. Is that a good option? What are other options? He can dribble and shoot and knows basic rules but has not played on a team before. Is it already too late for him to learn this sport?
