The problem with the USA is the Super League and the National Division 1. Many say that the Division One is better. There are two different competitions... The costs of Super League are high for the clubs so many have opted to player in the other comp. USA Rugby wants to replace both with a professional competition and I think they will succeed. They need tv more than anything else and they are getting it now. The crowds are okay for now and are only gong to get better. I am interested in the format that would be used in a professional USA League. My guess is an eastern and western conference combining some teams. Some are obvious like the Chicago Lions and the Chicago Griffins. I´d not move the east-west divide across so that Texas is a part of the east and have 12 teams split into these zones just like in the NBA.
West - San Francisco, Los Angeles (inc Belmont Shore, etc), Las Vegas, Denver, Salt Lake City (Sandy), Seattle (Old Puget)
East - Chicago, New York, Atlanta (Life University), Boston, Dallas, Carolinas
Canada could be on board with the same four teams from the Canadian Rugby Championship involved.
Many already have good stadiums. Denver and Salt Lake City for instance.
