Dallas Cowboys owner Jerry Jones said on Monday that he is not open to selling the team he has owned for three decades. The Cowboys are the NFL's most valuable team and have an estimated operating income of nearly $469 million.

"I know that I wouldn't sell the Cowboys for $10 [billion]," Jones told Yahoo News.

Jones was interviewed at the New York Stock Exchange in lower Manhattan. The Cowboys face the New York Giants on Monday night at MetLife Stadium in New Jersey.

The Cowboys are reportedly valued at $8 billion by Forbes, a figure that has doubled in the last five years. The Cowboys are considered to be the most valuable sports club in the world.

A reason Jones said he has no intention to sell the team is due to the league's limited ownership. There are 32 NFL teams and according to Forbes, the least valuable is the Buffalo Bills at $2.27 billion.

Jones said that money was not a factor in his purchase of the team in 1989 for $150 million.

"What I wanted to do was coach football. I never felt that I could be involved in something that would have economic viability," he said.

With Amazon's foray into football and streaming, the league has seen increased audiences, a topic Jones discussed in the interview.

"I think Thursday night's audience was epic. Frankly deserves special notice," Jones said.

With the league's $1 billion-a-year deal with the retail giant, streaming appears to the way forward. The picture has "never been better" for the NFL, Jones said.

In a surprise to many football fans, Jones also issued some positive sentiments to the Philadelphia Eagles, a rival of the Cowboys.

"I'm impressed with the Eagles," he said.

"I actually like Eagles fans because they are so passionate. They are so mad at it," Jones said with a smile.

Jones, 79, a major investor in energy company Comstock Resources, has seen his $1.1 billion investment double. His current net worth is estimated at $11.2 billion, according to Bloomberg's Billionaire Index.
