Regardless of why Fassel decided to leave Dallas, this is still a significant loss for the Cowboys. Under his guidance, the team has had one of the best special teams units in the NFL, and his departure leaves a substantial void that the new head coach will need to fill.

The first of Dallas’ assistant coaches from last season is on the move, as John Fassel is headed to Nashville.

As the team continues its search for a head coach, multiple outlets reported Monday that John Fassel will become the next special teams coordinator for the Tennessee Titans. Fassel spent the past five seasons at the same position in Dallas, serving the entire tenure of former head coach Mike McCarthy.
