The Dallas Cowboys are the NFL's most valuable team for the seventh straight year, according to Forbes' annual team valuations. The Cowboys are worth $2.3 billion, outpacing the Patriots ($1.8 billion) and Redskins ($1.7 billion) for the top spot.
According to the report, NFL franchises are, on average, worth $1.17 billion, a 5 percent increase from last year. That value tops the average values of the top 20 soccer teams in the world ($968 million), the 30 Major League Baseball teams ($744 million), the 30 NBA teams ($509 million) and the 30 NHL teams ($282 million).
Forbes' Mike Ozanian writes that the increase in average value comes mostly from a 3.6-percent increase in revenue. The Cowboys topped the league with $539 million in revenue last year.
The only team in the NFL to post an operating loss was the Detroit Lions. The Raiders are the least valuable franchise, with a value of $825 million.
