Unfortunately there are no silver bullets.

Maybe this is a good use for the "shotgun approach", then. Basketball for people who want it, games for people who want it, etc. If you want people join team building events, I don't think the right approach is to mandate one thing, but to give people choices & let people own their team building experience.

I also think the flip side of this is that management also has to understand that it's fine if not every single team member contributes to every team building activity - my team had to give our manager that feedback recently.

definitely, but then you also miss the opportunity to build relationships between someone who loves basketball and someone who does not. So everything is a trade off :)
