Dallas is bringing in veteran coach Mike Pettine as a senior defensive assistant to address a beleaguered start to the season, aiming to inject experience and speed up improvement under first-year coordinator Christian Parker. Pettine’s hiring, coordinated with coach Brian Schottenheimer, reflects a shift after a string of underwhelming defensive results and the realization that personnel changes alone may not suffice. The move comes amid a season already highlighted by the unit leading the league in yards allowed and lacking interceptions, with the staff signaling a broader effort to retool across all three phases. The team expects Pettine to integrate quickly, possibly from the coaching booth, as part of a broader set of adjustments to come.
