"It's been a little bit gruesome honestly," he said. "Now that it's getting closer to senior year and a lot of people are making decisions and committing, there's more of a stress on where I'm going to go. It's getting a lot tougher."
Rutgers was one of the first to offer Preston, who said his relationship with the staff stands out.
"Rutgers is a great place," he said. "I've been in contact with the coaches a long time and they've been recruiting me since it started. I believe Rutgers is great, but I just have to see more for myself."
West Virginia and Louisville are two other schools he is eager to see in person.
"They've both been recruiting me pretty hard," Preston said. "[West Virginia] has a great coaching staff and I just really like the speed and the kind of players they're recruiting. … [Louisville] is kind of the same with the coaches. They're great to talk to and they're showing a lot of attention."
For now, Preston plans to take all five official visits before a decision.
Preston camped at both Miami and Florida this spring and does not have any other plans going into his training camp at Jensen Beach.
"I think they were both great camps," he said. "I got to meet my position coaches at both programs and all of the coaches. I enjoyed myself.
