The Dallas Cowboys haven't finished any of the past 17 seasons on top, but they will start in first place on Forbes' NFL Team Values list for the seventh straight year.

Jerry Jones' team is worth $2.3 billion, the magazine said in the list it published Wednesday morning. The Cowboys, who last won a Super Bowl in 1996, are the only NFL team worth more than $2 billion.

The New England Patriots ($1.8 billion), the Washington Redskins ($1.7 billion), the New York Giants ($1.55 billion) and the Houston Texans ($1.45 billion) round out the top five. The entire NFC East is ranked among the seven most valuable teams, with the Philadelphia Eagles coming in seventh ($1.31 billion).

Forbes says the average NFL franchise is now worth $1.17 billion, more than the mean valuation of the world's top 20 soccer teams ($968 million). The average NFL franchise also is worth more than the average MLB team ($744 million), NBA team ($509 million) and NHL team ($282 million).

The Cowboys' $500 million lead over the Patriots was widened this offseason thanks to AT&T buying the naming rights to the 4-year-old stadium for more than $400 million. The team is the only team in the league that opted to distribute and control its merchandise supply chain.
