The Tennessee Titans will officially conduct the search for their next head coach when the regular-season campaign concludes. When a new coach is appointed, they'll work towards hiring their assistant coaching staff. The Titans will essentially fire the majority of coaches currently on staff.
The Titans' current staff is still one that was put together by Brian Callahan. Interim head coach Mike McCoy, and all three coordinators, were originally hired by Callahan. A new head coach will prefer to replace them with his own hand-picked assistants.
A small handful of Titans assistants may be retained. Special teams coordinator John "Bones" Fassel is probably high on that list. Maybe a positional staffer or two, like Luke Stocker (tight ends) or Frank Bush (linebackers) will also survive. One coach who is essentially guaranteed to be relieved of his duties is offensive coordinator Nick Holz.
Titans OC Nick Holz is as good as gone
Holz was hired by Callahan in 2023. The two shared a long history together. They both attended De La Salle High School in Concord, California up until 2001. Holz got into coaching at Nebraska in 2007, when Brian's father Bill Callahan (now-former Titans offensive line coach) was the program's head coach.
Holz and Callahan first coached together with the Raiders in 2018. When Callahan decided to call plays in Tennessee, he needed an OC he could trust to handle the behind-the-scenes duties of the job. He unsurprisingly appointed Holz, who had zero play-calling experience in the NFL.
When the Titans stripped Callahan of play-calling after Week 3, the responsibility was handed off to quarterbacks coach Bo Hardegree. Multiple sources confirmed that decision was made above Callahan's head. His personal preference was for Holz to take his place.
When the Titans fired Callahan three weeks later (Week 6), the initial expectation was that Holz would be dismissed alongside him. Surprisingly, that did not happen. The Titans probably decided the offensive coaching staff was shorthanded enough as is, pushing them to keep Holz for now.
It's painfully obvious that Holz has stayed in a caretaker's role out of pure necessity. It's almost a locked-in guarantee the Titans will fire Holz once Callahan's head coaching successor is officially appointed. The countdown is on.
