Start with examples:
- How to attack zone defence? (tagged Basketball)
- Is it possible to effectively practice zone defence in basketball if you don't have 10 people? (also tagged)
Now the question is, should we encourage adding the name of the sport in the question title or is the tag sufficient enough?
My own view is that having the sport in the title helps because that is the first thing you read. It saves you looking through tags if it is unclear to you what the question is about.
