Randy Gregory reminded NFL fans on Tuesday that no free agency deal is done until a contract is officially signed.Originally, it was announced that Gregory was planning to rejoin the Cowboys on a five-year deal worth up to $70 million. ESPN's Adam Schefter and others reported that Gregory was expected to get $28 million guaranteed as a part of the contract.Cowboys are re-signing DE Randy Gregory to a five-year, $70 million deal that includes $28 million guaranteed, per source. Adam Schefter (@AdamSchefter) Cowboys fans were excited to have Gregory back. He is coming off one of his most productive NFL seasons and logged six sacks in 12 games for the team last year. With Demarcus Lawrence Saquon Barkley Jersey returning and Micah Parsons still on a rookie contract for four more years (including a fifth-year option), it seemed likely Dallas would once again boast a top-notch pa s rush.However, just about two hours after Gregory's signing was announced, word leaked out that he changed his mind. He opted to sign with the Broncos instead of the Cowboys, and that marked the first reported deal of 2022 free agency to fall through.Why did Gregory choose Denver over Dallas? It all boiled down to di satisfaction with the Cowboys' proposed contract.LIVE:Why Randy Gregory declined Cowboys' contract offerGregory's choice to sign with the Broncos over the Cowboys was due to a contract dispute with Dallas. It wasn't about how much the Cowboys were paying Gregory, though. reports that Gregory is getting the same five- Leonard Williams Jersey year, $70 million deal with Denver that he would have gotten with Dallas.So, what was it about? It was about contract language, as NFL Network's Ian Rapoport explained.And so its the not the that are in agreement with Randy Gregory. My understanding is Dallas insisted on contract language that Gregory did not like protecting themselves. So he heads to Denver. Ian Rapoport (@RapSheet) What was the hold-up with the language? reports that the contract contained "salary forfeiture language" that is "standard to the Cowboys but not commonly used by other teams."The language in question is likely related to Gregory's history of suspensions. The 2015 second-round pick has frequently violated the NFL's substance abuse policy during his career, and mi sed 14 games in 2016, the entire 2017 season, two games in 2018, the entire 2019 season and six games in 2020 as a result of failed drug tests.Gregory hasn't been suspended since the beginning of the 2020 season, but it's understandable that the Cowboys would want to protect themselves given his previous i sues. Dallas had been left in the lurch from a personnel perspective by his previous suspensions; the team wouldn't want to be in the same scenario with more guaranteed a sets tied up in him.That said, reports that the Cowboys had an agreement with Gregory but "attempted to change the contract" after they had brokered the deal. That didn't sit well with Gregory, so he went to the Broncos.MORE: Why the Broncos signed Randy Gregory over Chandler Jones, Von MillerThe Broncos were tied to a couple of other pa s rushers on the free-agent market in Chandler Jones and Kayvon Thibodeaux T Shirts former Denver star Von Miller. However, they ultimately signed the 29-year-old Gregory instead of Jones or Miller.Why did the Broncos roll with Gregory? Well, according to , Gregory was, simply, Denver's top target among the free-agent pa s rushers.Werder also noted that Harry Carson Jersey the Broncos thought they had a deal before the Cowboys and Jerry Jones swooped in to try to keep Gregory.Source: ranked Randy Gregory as top edge in UFA over Chandler Jones. Believed they were close to deal last night, then owner Jerry Jones recruited the hell out of him. Cowboys reportedly attempted to change contract after agreement. Broncos became the choice. Ed Werder (@WerderEdESPN) It's interesting that the Broncos would prefer Gregory. He has just 16.5 sacks in 50 career games while Jones has 107.5 in 136 and Miller has 115.5 in 150.That said, Gregory is the youngest of the bunch at 29. Jones is 32 while Miller is about to turn 33. Perhaps Denver just wanted to avoid paying a ma sive contract to a veteran already in his thirties who could decline in the deal's latter years.Gregory has a better chance of remaining in his prime during this contract than Jones and Miller do. But in order to live up to it, he will need to stay on the field.MORE:How could Randy Gregory sign with the Broncos after signing with the Cowboys?Gregory Saquon Barkley T Shirts didn't actually sign a contract with the Cowboys. He was still a free agent even after agreeing to terms with Dallas.The first 52 hours of NFL free agency are part of what's called the legal tampering period. During this time, teams are officially allowed to have conversations with agents and players to lay out the groundwork and terms of each deal.However, new contracts aren't officially allowed to be signed until the start of the new league year.

It also can't be made official until 4 p.m. on Wednesday, so his decision should continue to be monitored.
