As Dan Snyder's ownership of the Washington Commanders has come under increasing scrutiny, he has reportedly told his inner circle that he has dirt on his fellow owners, coaches, executives he is prepared to use.

Snyder recently told a close associate that he has gathered enough secrets to "blow up" several NFL owners, the league office and even commissioner Roger Goodell.

"They can't f--- with me," he has said privately.

Snyder has previously instructed his law firms to hire private investigators to look into other owners, including Jerry Jones. One owner was told by Snyder directly that he "has dirt on Jerry Jones," a team source told ESPN, though the nature of the information was unclear. 

"The NFL is a mafia," he recently told an associate. "All the owners hate each other."

"That's not true," one veteran owner says. "All the owners hate Dan."

League sources say the NFL is aware that Snyder has claimed to be tracking owners. 

Several owners say that they see the threats about damaging dossiers as a desperate tactic intended to scare owners from voting to remove Snyder. "He's backed into a corner," says a veteran owner who says he's aware Snyder has gathered dirt on some owners. "He's behaving like a mad dog cornered."

At least 24 owners are required to force Snyder to sell his team, a fate that he has told multiple sources he will never accept.
