He spent his Saturday on the Georgia Tech campus, working out with college prospects from a variety of states at the Scout.com Southeast Elite 150 Camp.
"It went all right," says 6-5 1/2, 310-pounder, who drilled with the defensive linemen in Atlanta. "I felt a little rusty on the one-on-one drills because the whole spring my coaches had me practicing on the offensive line and we had a scrimmage the night before the camp and they had me going both ways so I was a little tired when I got here.
"After the first few times I went against these guys I got better," he adds. "We are putting a new offense in so that is why I just worked on the offensive line this spring. Also, I had to stay up all night because I had a new niece (born), but that is all right because she is my pride and joy. I wanted to work on defense at the camp because I hadn't been playing any defense in practice."
Harmon is shown at Saturday's camp.
Harmon, who was impressive at an Auburn camp last summer after his sophomore season, says, "Clemson and Georgia are my leaders and Auburn is number three right now. Number four is Florida and number five is open. Schools still have a chance with me if they come in and talk about depth charts and academics because that is what opens up the eyes of my mom and dad.
"If I can come in and have a chance to start as a freshman, that is what I am interested in," the big lineman says.
A three-sport athlete at Jefferson County High in Louisville, Ga., football is the one that will be his ticket to college.
"I am playing basketball and track," he points out. "I am the center in basketball. I started off slow, averaging about five points. We had a Christmas tournament against some bigger boys who were looking at me, thinking they were going to manhandle me, and that is when my game stepped up. Starting then, and for the rest of the season, I averaged 20 points per game.
"In track I throw the shot and the discus. I am not all that good in the discus. I was third in the shot in the region. Two guys beat me about an inch. I threw 54 (feet) something."
Harmon, who says he has a goal to drop weight over the summer and open the season at around 290 pounds, plans to stay busy in the coming months. "I am going to camps at Auburn, Georgia, Florida, Marshall and I am going to try to make it to LSU."
