The Dallas Cowboys have been working to improve their defense after a poor performance in the previous season. This effort has been ongoing throughout the offseason. The team has made some changes, including hiring a new defensive coordinator, Christian Parker, after a thorough search.

Further details about the team's progress and plans are available from the Waco Tribune-Herald, which has been following the Cowboys' offseason activities, including their first camp practice where a notable incident occurred involving a free agent safety.
