I see the bolded part as a positive for Omaha having a major league franchise. Imagine all the people that travel to KC, Minneapolis, Denver and Chicago to see their team play or are fans of teams in those cities. I could easily see a large majority of people taking to and supporting a pro team here.
I think an NBA would be the most successful franchise. You have 2 teams in this state that have had moderate to above average success that are in the top 10 in the nation for attendance. Might there be some lesser attended games when the bad teams come to town? Yes, but imagine ticket prices and the downtown area for when the big name teams and players show up to Omaha. I for one would be all in on this deal.
