According to a source, Jones is considered a "great guy" in the organization. He is expected to play a key role in the Cardinals defense this season. The contract details of its players are not usually disclosed by the team.Jones could end up in Arizona, and then be eligible for free agency in 2022. However, that may not end the discord.Jones, who was due $15.5million in the last year of his contract, emerged as the best pass-rusher in the game, recording 49 sacks between 2017-19. He was limited to five games last year due to a biceps injury.The Cardinals have given significant money to other players, including Watt's $28 million contract this offseason. DeAndre Hopkins, wide receiver for the Cardinals, was granted an extension last year by the team. This made him the highest-paid receiver in the game, despite the fact that he had multiple years remaining on his original contract. Safety Budda Baker also received extensions, which were some of the most lucrative contracts for his position.In 2016, the New England Patriots traded Jones to the Cardinals.
