That's a good list. A couple of questions/comments:
The mention of Vipers brought to mind the now-defunct XFL team from Las Vegas. Are you contemplating opting for an alternative nickname, or do you intend to stick with the Vipers?
In the Northwest Division, there are three newly added expansion teams, the highest number among all divisions. Have you considered relocating one of these expansion teams to a different division?
I love seeing the Spirits back in the NBA and great alternative name choice for Memphis (I remember it was a soccer team name in the 1990s).
