What happened: Mike Pettine was in Italy with his wife when Christian Parker called about a senior defensive assistant role. Pettine previously worked with both Parker and Brian Schottenheimer, framing the move as a reunion tied to Parker's defensive staff.

Why it matters: Dallas added an experienced voice to support Parker amid scrutiny of the defensive operation. The reporting detail drew attention after Schottenheimer said Pettine answers directly to him rather than Parker.

What to watch: Watch how Pettine's booth role functions on gameday and whether Dallas clarifies the chain of command.
