Domain Model - confusion

My assignment shows a many-to-many relationship between two business entities ( e.g. a Team consists of 1 or more Players. A player can belong to one or more Teams ) but the use cases given seem to suggest only a 1-to-1 relationship or at most 1-to-many relationship. Is it possible that the association could be realized only by other use cases (not given in the assignment) or I have not understood the problem at all ?

If there are indeed other use cases required to justify the model do I need to solve for them ?

A clear understanding of the assignment and making your thought process in favor of given assignment would get you more points for sure. I satred my assignment in first 3 days, I had similar thoughts about my assignment and then I realized that assignment's BDM is good enough. It was me, who was trying to think, I am right and assignment is wrong but in reality both may be true in different contexts. Try to get yourself in the same context as assignment.
I found a beautiful pie. And a tiny ad:
