After thanking friends, family, coaches and God, Hart came with his pledge: "After much reflection with my family and by myself, I am proud to say I've committed to the University of Tennessee."
The Memphis native ranks by Scout as the No. 2 outside linebacker in the Volunteer State, No. 22 in the South and No. 68 nationally. Hart took an unofficial visit to Knoxville back on Oct. 25 to see the Big Orange host Alabama at Neyland Stadium.
Alabama, Georgia, LSU, Ohio State and Ole Miss all showed interest in Hart before he honed in on a career with the Volunteers.
The 6-foot, 215-pounder becomes Tennessee's first linebacker committed for the 2016 recruiting cycle. In the 2015 class, the Orange & White signed Scout three-star Austin Smith and four-star Quarté Sapp at outside linebacker to go with four-star middle linebacker Darrin Kirkland Jr.
The Vols have seen quite a few changes to their '16 group in June as Hart makes the fourth prospect to choose Tennessee. Offensive lineman Brodarious Hamm and cornerback Bailey Phillips backed off their decisions to be Vols.
After playing for a pair of TSSAA Division II Class AA state championships, the Owls came up a game short of the final in 2014, losing to powerhouse Ensworth 27-24.
Hart totaled 196 solo tackles, six sacks and two interceptions combined from his sophomore and junior seasons. He was a teammate of of Tennessee offensive tackle signee Drew Richmond, who arrived on Rocky Top earlier this month.
