The 6-foot-4, 285-pound Holley, who holds close to 20 offers, is speaking with assistant coaches from Alabama, Florida State, Penn State, Rutgers, Ohio State and Notre Dame with the most regularity, but he continues to speak with many other assistants as well.
"It's hard to say," Holley said of which schools are after him the most. "A lot of schools are coming after me real hard. If it's not a (quiet) period, a school will hit me up every day. Other schools will be calling or hitting me on Facebook.
"I've been talking to (Alabama assistant) coach (Mario) Cristobal a lot, (Florida State assistant) coach (Sal) Sunseri, (Penn State assistant) coach (Larry) Johnson, (Rutgers assistant) coach (Jim) Panagos, (Ohio State assistant) coach (Ed) Warriner. Those are coaches that talk to me a lot. I talk to Notre Dame a lot. That is definitely an option of a school I can go to."
Holley has been to Rutgers and Penn State, and he has been trying to arrange visits to schools in Florida for the last few months and is hopeful of getting there in June.
"We're trying to hit Florida, Miami and Florida State," Holley said. "That's probably going to be the next trip I make. Things change, but that's definitely a place I'm going to hit. I'm, trying to wait to until I see everybody and then fill out schools and coaches and I'll know after that."
However, at this point Holley isn't ready to declare favorites.
"No top (schools) right now," Holley said. "I'm trying to wait until I do more visits and do some more research on schools, and probably by the end of summer I'll be able to start narrowing things down. It will probably toward the middle of the season or end of the season when I make a decision."
Meanwhile, Holley is making his mark on the camp scene. He was dominant as a defensive tackle at Sunday's Nike Football Training Camp, and it comes a year after he returned to football after playing basketball the first two years of his high school career.
"I still have so much to learn," Holley said. "It's my first year of playing football, and this is my first official combine view of how things are set up. It was a really good day. I came out, worked hard and competed with everyone else and did what I had to do."
