Hello
My comments:
unless I misunderstood the complete structure...
property: athlete, coach should be reified to become a class, a sub-class of Person.
-I am sure that you find something interesting to say about those persons other than just a member of a team
-Messi is a member of FCB, is member of Team Argentina, was born in Rosario, Argentina...
-Messi:athlete <-- sponsors --> Predator:Product < --- produced by --> adidas:Vendor
