Just because the auction of the Buffalo Bills is having a tough time drawing bids above $1 billion two years after the Cleveland Browns sold for $987 million, and just weeks after the National Basketball Association’s Los Angeles Clippers were sold for $2 billion, doesn’t mean the National Football League is losing its status as the most valuable sports league in the world.

To the contrary: The average NFL team is currently worth $1.43 billion, the highest value in the 17 years Forbes has tracked professional football team finances. The $1.43 billion average is 23% more than a year ago, the biggest year-over-year increase since 1999.

Forbes’ team values are enterprise values (equity plus net debt) and are calculated using multiples of revenue that reflect each team’s current stadium economics (with adjustments for pending new stadiums and renovations).

In our most recent reports on the other top sports, the world’s 20 most valuable soccer teams (comprised mainly of clubs from the top English, Spanish, German and Italian leagues) had an average value of $1.05 billion, Major League Baseball teams had an average value of $811 million, followed by the NBA, with an average team value of $634 million.
