Seahawks safety Jamal Adams, Patriots cornerback Stephon Gilmore, Dolphins cornerback Xavien Howard, Cardinals edge rusher Chandler Jones and Packers quarterback Aaron Rodgers skipped the mandatory June minicamp because of issues with their respective teams. Tight end Zach Ertz and quarterback Deshaun Watson likely would have done the same had the Eagles and Texans held minicamp.
The issues fall into two categories. These defensive players have been unhappy with their contracts and would like new deals. Adams is the only one expected to sign a contract extension before the regular season begins. Ertz, Rodgers and Watson have wanted to be traded.
All of the players reported to training camp on time. The Packers were able to satisfy enough of Rodgers' concerns by making adjustments to his contract, including voiding the final year (2023). Rodgers isn't being traded this year.
Training camp holdouts by players under contract are largely going to be a thing of the past because of more severe penalties in the 2020 NFL/NFLPA Collective Bargaining Agreement. Teams are required to fine players who aren't on rookie contracts $50,000 per day with training camp absences. Players on rookie contracts, like Adams, are subject to a $40,000 daily fine.
