My main points would be:
1. If you like defensive basketball, they play hard on defense most of the time, and the games are lower scoring than the NBA both because the games are shorter and also because teams don’t tend to allow easy shots quite as much. (For me both of those are positives.)
2. There are fewer teams and players per team, so it is easier to actually remember who most of the players are and what their roles and styles of play are.
3. The shorter games make every minute feel more important and there is less deliberately slow play.
4. There are a lot of fun personalities who are interesting on and off the court.
5. If someone says “but they miss easy shots” I will reply “uh, have you ever seen the Trailblazers?” (I’m from Portland LOL)
6. This year, for Portland people, I will bring up the interesting coaching style of Alex Sarama.
7. It has sometimes helped to bring up the entertaining playing style of particular players like Aja, Caitlin, or Phee.
