Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

Someone already commented on the fact there are no draws in basketball. Also, the expected output string is ugly. Rather than using "Points" for "marks in our ranking system," it would be less confusing to use "Marks" or something, since game scores are measured in points. And while the NBA website itself doesn't even track cumulative scoring, a convention in other sports is to use points for and points against. "Conceded" just sounds weird.
