It's been more than three weeks since Tennessee fired coach Butch Jones. One athletic director upheaval and several swings and misses on the coaching carousel later, the Vols could finally be closing in on a new head honcho.

It appears as though Tennessee is focusing in on a trio of SEC defensive coordinators: Alabama's Jeremy Pruitt, Georgia's Mel Tucker and Auburn's Kevin Steele. The latter two have already had two interviews with new Vols athletic director Phillip Fulmer, per ESPN's Chris Low.

Pruitt in particular seems to be gaining steam as of Wednesday morning.

All three coordinators are coming off of successful seasons. All three also have ties to Nick Saban's coaching tree.

Pruitt has done an excellent job at Alabama. The No. 4 team in the College Football Playoff led the country in scoring defense for the second straight year. The Crimson Tide defense was also No. 1 in the SEC against the run and red zone scoring conversions.
