Guiding sports assessment

I’m ready to provide guidance on how to assess common sports criteria, like blocking in basketball or tackling in soccer. I think it would be helpful to structure these criteria while reminding the user that the final judgment relies on referees and specific rules. I could also ask if the user wants frame-by-frame analysis of a video, offering to annotate if they have one. Let’s consider the tools available and keep our advice non-medical and non-legal!
