Aiken is a 6-3, 240-pounder rated a 3-star prospect by Scout.com. He posted more than 100 tackles last fall, including 13 sacks. Deleon is a 6-1, 260-pounder who registered 89 stops last fall, including 28 tackles for loss and 7 sacks.
Aiken reports offers from USC, Michigan, South Carolina Clemson, Bama, Auburn, Georgia, Tennessee, Virginia Tech, North Carolina, North Carolina State, Georgia Tech, Louisville, East Carolina, Wake Forest, Duke, Colorado, Florida Atlantic, Illinois and Tulane.
As fate would have it, the South Carolina assistant recruiting Aiken is former Vol running back Jay Graham. Graham assumed the role when Shane Beamer, a former Vol graduate assistant, left the Gamecocks to join the staff of his father, Frank Beamer, at Virginia Tech.
Aiken says he has no leaders at this time. Deleon, who holds nine scholarship offers, says Tennessee is in his top three, along with Illinois and Colorado.
Aiken expects to make decision by late summer so he won't be distracted during his senior season of high school ball.
"I'm going to try to take as many visits as possible and see as many schools," he said following his recent Tennessee tour. "There's more schools, like Tennessee, that it will be my first time going there."
Like many of the young men who visited on Junior Day, Aiken was impressed with Vol head man Derek Dooley.
"He's a good guy, man," the prospect said. "He came over to the table and told me he wants to see me back up here in the spring and during the summer for camp. I like him a lot. He's a straight-forward guy and he showed us a lot of attention while we were here."
Given the number of schools pursuing Aiken, he may be unable to settle on a program by his target date of late August.
"I'll try to make the decision this summer before the season starts," he said. "If not, I'll make it after the season."
Tennessee apparently made a good first impression.
"It went pretty good," he said of his visit. "I got to see something I'd never seen before. This was my first time ever to come to Tennessee."
If Vol staffers have their way, it won't be his last.
