According to Forbes, the average National Football League team is now worth $1.04 billion, 1.4% more than last year. During the 2010 season average revenues for the league’s 32 teams rose 4% compared with the previous season, to $261 million. Although operating income (earnings before interest, taxes, depreciation and amortization) fell 8.1%, to an average of $30.6 million per team due to higher costs for stadium operations, training facilities and marketing, the new collective bargaining agreement will give owners a bigger slice of overall revenue.
