Those top five programs include Notre Dame, defending national champion LSU, Texas, Georgia, and Duke, with the Fighting Irish sitting atop the list.
"I like the tradition of it all at Notre Dame," said Duncan. "Everybody knows what you're talking about when you say 'Notre Dame football.' It's a Catholic school, and I'm a Catholic boy. I've always wanted to go there, and it's a dream that's coming true. I'd say there's an 80% chance I'll go to Notre Dame. They have a solid lead and I'll be going to camp there on June 29th.
"LSU, they're the national champs. (DB) Coach Kirby Smart says they like my footwork and the way I move. I'm going there for an unofficial visit with my family on 7/19.
"Texas said they were going to offer me, but I don't think they have. I won't be able to go there this summer because my schedule's too busy.
"Georgia (July camp) sends letters every now and then. I'd like to go there, but it doesn't feel like they're going to offer me.
"Duke (June 19th one-day camp) was the first school to offer me. The quality of their education is a big turn-on.
"I'm looking for a school to win; everybody hates losing. The education is important too. I'd prefer a predominantly passing offense. I really don't know when I'll decide, but I'd like to decide before my SR year. I'd have to see the campus of a school before I choose. So far, I've only been to Duke and Georgia but I'd like to play (my SR year) knowing where I'll go.
So what makes him such an attractive prospect?
"My feet and flexibility are my strengths. I'm able to move quickly because of my flexible hips."
Off the field Duncan has already qualified with a 1080 SAT and a 3.4 grade point average.
