With the Sounders selling out their entire season, it’s easy to forget that the rest of the MLS is not sharing the same attendance success.
BigSoccer.com has a good article about how Frisco, TX (suburn of Dallas), used their MLS squad as a way to get an entire community complex developed, and how everything works together in a nice synergy. Perhaps there’s a way to do something similar with a basketball/hockey/concert arena type complex in Seattle?
