There seems to be another plot twist in the potential Jon Gruden to Tennessee situation.

Tennessee reportedly has “considerable reservations” about hiring Gruden as the Volunteers’ next head coach, according to a Friday report from Dennis Dodd of CBS Sports.

Concerns about Gruden are over the fact that he hasn’t coached at any level of football in nine years and hasn’t been on a college football sideline in 26 years, the report noted.

“Also, Gruden was basically a .500 coach (57-55) in his seven years with the Tampa Bay Buccaneers even after winning the Super Bowl in his first season with the Bucs in 2002,” the report said.

Dodd’s source wished to not be identified because of the “sensitivity of the search process.”

“This is not to say Tennessee would not consider hiring Gruden,” the report added. “It’s just that the Vols’ concerns are real.”

Dodd also mentions Oklahoma State head coach Mike Gundy and former Oregon coach Chip Kelly as potential candidates for the job.

Knoxville has been in a frenzy in recent days, with the overwhelming majority of the vocal fan base seeming to want Gruden.

For many, it’s “Gruden or bust.”
