For the second time in less than a week, Tennessee added to its 2020 recruiting class Wednesday by landing a longtime top target.

Three-star senior safety Mordecai McDaniel of St. John’s College High School in Washington, D.C., announced Wednesday that he has committed to the Vols, celebrating his 17th birthday by choosing Tennessee over Penn State and Florida after taking official visits to all three schools over the past five months.

The 6-foot-1, 195-pound McDaniel gave the Vols their 15th known commitment for the 2020 class and their second in six days after Top247 defensive end/linebacker BJ Ojulari of Marietta, Ga., announced his commitment to Tennessee on Friday.

McDaniel, who has received scholarship offers from nearly 20 schools, is ranked by 247Sports as the No. 385 overall prospect and No. 32 safety in the 2020 class.

The Vols extended an offer to him in January and have been among his top choices for months. He included them in the top five he announced in early April, although he hadn’t been to Tennessee’s campus at the time.

An official visit to Knoxville the weekend of June 7 allowed him to take his first look at the Vols, and he made it clear that he felt comfortable at Tennessee right away.

“All I’m going to say is that I can see myself balling out at Tennessee,” McDaniel told 247Sports’ Brian Dohn at the time.

He said he also was impressed by the “family” atmosphere throughout the Vols’ program.

“The players are family,” McDaniel said in June. “You can see the brotherhood that they have made. … The people stood out the most to me (with) how they treated me and each other. You see the family that is built.”

Tennessee coach Jeremy Pruitt’s message to McDaniel during his official visit to Knoxville, he said, “was really to just make the right choice for me and my family.”

McDaniel ultimately decided that was to play at Tennessee, where he’s hoping to run track in addition to playing football.

He won the District of Columbia State Athletic Association championship in the 55-meter dash during the indoor track season with a time of 6.54 seconds. He also has been timed at 21.99 seconds in the 200 meters and 34.33 seconds in the 300 meters, according to milesplit.com.

“That is one thing that is going to be an (important) aspect for me — the track team,” McDaniel told Dohn last month, when he referred to Florida, Penn State and Tennessee as “my top three.”

“I want to do that in college.”

The Vols have told McDaniel they have big plans for him in their secondary, where he will join four-star safety Keshawn Lawrence of Nashville, Tenn. — a top-100 prospect nationally — four-star cornerback Art Green of Hutchinson (Kan.) Community College and three-star cornerback Lovie Jenkins of Ocoee, Fla., as the fourth projected defensive back in Tennessee’s 2020 class.

“They say that, by the time I get there, it will be a good time to be playing (for Tennessee), and I could get (early) playing time as well,” McDaniel told Dohn last month. “The coaching staff there really wants me, and they would use me early.”
