Randy Gregory is now a member of the Denver Broncos, and Jerry Jones is not happy about it. The Dallas Cowboys seemingly had a deal with Gregory in place, announcing it on the team's social media channels, before Gregory changed his mind just hours later.According to ESPN's Ed Werder, a source told him that there was salary-forfeiture language that the organization puts into its contracts. This is what led to the 29-year-old deciding against the deal, as it was not part of the contract that was originally agreed upon.Despite being hands on with the deal, Jones did not have a hand in the contract change, according to Patrik Walker of CBS Sports.Walker posted on Twitter:"For the record, Randy Gregory accepted [much] less money to agree to terms with the #Cowboys. At one point, the gap between their offer and others were roughly $4M-$5M. They closed the gap enough, not completely, to the point he agreed."Jerry Jones was passionate about getting this deal done and was largely responsible for it coming together. The post-agreement change was not his idea/doing. I'm told Jerry Jones is livid."Patrik [No C] Walker@VoiceOfTheStarMore: Jerry Jones was passionate about getting this deal done and was largely responsible for it coming together.

After numerous setbacks throughout his career, the 29-year-old was showing signs of being the game-wrecker the Cowboys needed.He totalled six sacks in 12 games, while recording 19 tackles (four for loss) and 17 quarterback hits. There is now a glaring hole in the Dallas defensive line, but it appears that the Cowboys are already interested in a replacement: Von Miller.The 32-year-old is thought to be interested in joining the Cowboys, but as with most deals, it depends on the amount of money offered.Ed Werder@WerderEdESPNSource says the salary forfeiture language #Cowboys include in player contracts that led Randy Gregory to abruptly sign with #Broncos is standard to them but not commonly used by other teams. #Cowboys now have “high interest” in Von Miller depending on financial expectations.7:22 AM · Mar 16, 20221852291Source says the salary forfeiture language #Cowboys include in player contracts that led Randy Gregory to abruptly sign with #Broncos is standard to them but not commonly used by other teams. #Cowboys now have “high interest” in Von Miller depending on financial expectations.Acquiring the 32-year-old would be a welcome boost for Dan Quinn and the Cowboys' defense. Having Demarcus Lawrence, Micah Parsons and Von Miller, along the defensive front, would give opposing offense's nightmares.While there is still a lot to play out regarding getting Miller to Dallas, Jerry Jones is going to have to live with the fact that the Dallas front office tried to be a little too smart and ultimately cost the team a deal.Jones is fuming and rightly so.
