The 6-foot-4, 290-pound Holley also is yet to trim an offer list that exploded to close to 20 offers in the span of a few weeks, and isn't close to cutting schools.
"I'm going to do some official visits during my senior year, but during the summer there's going to be a lot of unofficial visits," Holley said. "All the schools are standing out in their own way because every school is different. I know when I went to Rutgers and Penn State, both schools were similar but they had their differences, which set them apart.
"Once I start making more visits, I will know (if any are standing out)."
Holley visited Rutgers and Penn State in February, made a return trip to Rutgers on Tuesday and he said he will be at Boston College on Saturday. He is also considering a trip to Syracuse, and wants to visit Florida, Florida State and Miami the week of April 15, but those trips are not set.
However, when Holley's unofficial visit tour hits high gear, he will know what he wants in a school because he is spending plenty of time thinking about it.
"I'm definitely looking at education first," he said. "You can go to a place, but if you can't get a meaningful degree and learn something, it doesn't mean anything. Also, it's how the coaches are, and the environment of the school and the vibe I get off of everything.
"I feel like I'm talking to everybody equally. I am just seeing what everyone has to offer."
Holley added he is in contact with Notre Dame, but despite current Irish linebacker Ishaq Williams being a Lincoln High graduate, it won't play a huge factor. Holley was at Christ the King when Williams played at Lincoln High, and the two don't really know each other.
"I hear a lot from Notre Dame," Holley said. "I get a lot of feedback on Facebook of how they're doing, and what they're doing. (Williams) was at the school not too long ago but I didn't get a chance to see him. I was at the city championships (basketball) press conference."
Holley also is not in a rush to make a decision.
"I'm going to do some official visits during my senior year," he said. "But during the summer there's going to be a lot of unofficial visits."
In addition to the aforementioned schools, among Holley also holds offers from the likes of Alabama, Maryland, Ohio State, Ole Miss and Clemson.
