NFL teams are always trying to upgrade their roster one way or another. They are continuously on the lookout for players they can acquire to do just that. It's a never-ending process and one that is continuously monitored 24/7, 365 days a year. Even now, after the 2025 NFL Draft and free agency, teams are considering trade/cut candidates around the league.
The Dallas Cowboys are no doubt still putting in the work for talent acquisitions to upgrade their roster and are more than likely monitoring the roster status of several potential trade/cut candidates from other teams.
