The 6'1.5", 177-pound Georgia product selected the Vols over the Georgia Bulldogs, Notre Dame Fighting Irish, Ole Miss Rebels and Mississippi State Bulldogs among others.
Callaway, who is the nation's No. 3 athlete and the No. 103 player overall in the 2016 class, has the ability to play wide receiver or corner at the next level.
However, as Ryan Callahan of GoVols247 reports, the Vols are recruiting him to play offense when he gets to Knoxville.
What exactly are the Vols getting in the Peach State speedster?
There's a reason why multiple Vols coaches—including head coach Butch Jones—were celebrating on social media shortly after Callaway made his announcement.
For starters, he's one of the most talented and versatile athletes in the 2016 class. As Callahan detailed earlier this month, the Vols coaching staff expressed how important of a target he was on his latest trip to Knoxville.
“[The Tennessee coaches] all said the same thing—how I could make an impact, and how they really wanted and needed me,” Callaway told Callahan. “I spent a lot of time with Coach (Zach) Azzanni, the receivers coach. We spent time with a lot of coaches—Coach Jones, (offensive coordinator Mike) DeBord, all them.”
Also a standout on the hardwood, as Barton Simmons of 247Sports details, Callaway is a raw specimen who has dominated on the prep level mainly due to his athleticism.
While there's a chance he may need some time to adjust to learning one position full-time, he has the instincts and playmaking ability that can't be coached.
Assuming he sticks at receiver, he possesses the size, speed, length and leaping ability necessary to create problems for defensive backs.
Receiver is a top priority since the Vols are losing three of their top six receivers on the depth chart, as illustrated by Ourlads.
Even though Callaway is joining a class that already features three other receivers currently committed, he could potentially find the field early if he's able to make a transition similar to the one rising sophomore Jauan Jennings did a year ago.
Regardless of where he fits in the Vols' plans long-term, his arrival on campus will give Jones and his staff a potential impact performer on offense, defense and even special teams.
