It's June 8. These as-yet unannounced teams that have (apparently) just been waiting for this league to come along have about nine months to get everything in order if they are going to kick a ball in spring 2018. It is not easy to sell 3-5k tickets per game in most places without a decent startup time. Plus, one might assume these would be markets currently without teams or with amateur teams, which presents challenges either way. I know for an absolute certainty that's not why.
