The most valuable are the Cowboys, Patriots, Giants, Redskins and 49ers.
The top five: Dallas $4.8 billion, New England $3.7 billion, the New York Giants $3.3 billion, Washington $3.3 billion and San Francisco $3.05 billion.
The Packers are worth an estimated $2.55 billion, 13th-most in the league.
The publication said the value of the Cowboys, who have been the most valuable National Football League team for the last 11 years, rose 14 percent over last year. Values increase with inflation, postseason revenue, rights fees and stadium renovations.
This year's gain boosted the average team's worth to $2.5 billion. Only one team, the New York Jets, had a value ($2.75 billion) that stayed the same as previous year. The magazine estimates the Bills' value at $1.6 billion. With Mercedes-Benz Stadium opening this season, the Atlanta Falcons had the biggest year-to-year jump from 2016 to 2017.
Despite rough times the last few years, the team is still one of the most valuable in all of sports.
