If an NFL team is worth 600 million (http://wiki.answers.com/Q/How_much_d...NFL_teams_cost - I know this isn't research, it was the first article I could find on a 5 second google search) and they make a yearly profit of just 5% that is about 30 million. I know absolutely nothing about what should be expected to be made in regards to percentages in businesses but I would think a profit of 5-10% of what it is worth yearly sounds about right. So a team like the Vikings worth 600 million should expect a yearly profit anywhere from 30 million to 60 million.
