He lost a power struggle with his Titan's GM, Ran Carthon. Word is, at one point he refused to work with Carthon and started making some of his decisions/changes w/o the owner's approval. It was pretty messy by the time he was fired. No GM will hire a coach they think will come after their job. Just as head coaches stick together, the same can be said for GMs. This is why he was interviewed for only a couple of openings with no offers.
Sources say Vrabel has not approached ownership with any concerns about the structure of the organization or his alignment with general manager Ran Carthon, who was hired from the 49ers in January 2022. Vrabel has continued to coach the team with the same passion as when he was hired in 2018. But he also has done little to shoot down reports and social media speculation about his displeasure with the trajectory of things in Tennessee.
rumors were rampant that a power struggle between Vrabel and Carthon finally came to a head, leading to ownership choosing one over the other.
“Some of those leaks last year about Mike Vrabel allegedly dominating Ran Carthon on decisions and around the office were right on the money," a rival scout told Athlon Sports for this year's
NFL preview magazine, on sale at newsstands now. "From what I heard, the owner simply got tired of the situation and empowered Carthon by kicking out Vrabes. Ran is a real boss now in Nashville and doesn’t have to walk around on eggshells anymore."
