Yes :D there may be sorting happening inside an aggregate entity and that membership in a collection needs to be checked whether we are dealing with objects or data structures. However the objects in a collection usually only serve one aggregate, eg. Match / Events. That's why ordering algorithm can be coded into a compareTo -method of that object inside the collection. No need to order based on exposed attributes.

Oh, OK. Yeah I agree with you; for modularity and stability, it's better to opaquely define how comparison should work than to expose data and let the user misuse and depend on that data. I think the big disagreement most people have with that idea is that encapsulation isn't always the most important thing in the world.
