The four-star tailback was on hand for the first home game of the Lane Kiffin era, and the atmosphere inside the Coliseum with the 81,375 passionate fans, left a lasting impression.
"It was amazing. It was mind blowing actually," Carlisle said. "I have never been to a game where the fans were so loud, and the tailgating beforehand just showed how loyal the fans were. The Trojan Walk, it was mind blowing, it was great."
While on the visit, Carlisle got the opportunity to see how the USC coaches and players interact, and how they prepare on game day.
"The coaches really seem to care for the players and they really want the best for the players. Coach Kiffin has set high expectations," Carlisle said. "The bar has been set high and only greatness is accepted. I really like that because I try to set standards of greatness for myself and always strive to be better."
His host on the trip was freshman wide receiver Kyle Prater, and as Carlisle explains, Prater gave him a good idea of what it's like to be a student-athlete at USC.
"He just went what I am going through right now," Carlisle said. "He was able to give me good advice and really give me a good feel of what the program is all about, and what he likes about it, and what to expect if I came there. He was a great host."
Along with getting a behind the scenes look at the football program, Carlisle was also very impressed with the academic side of USC, and as a Drama Major, the idea of spending the next four years in Los Angles gave him plenty to think about.
"I had a great time. I got to learn a lot about the school from the academic side of it to the football side to the traditions of the school," Carlisle said. "It was an overall great time.
"I would say three highlights were: learning more about my major (Drama), the atmosphere and the tradition of USC."
While some kids are just looking to have fun during their recruitment, Carlisle takes the process very seriously and is doing all the research he can before signing a letter of intent.
"I approach the whole recruiting process as a business," he said. "I have to come to a decision so I try to take in all the information I can. Business first, fun and games later."
So where does USC now stand?
"They are very high on my list. I would say that Stanford is my no.1. I am still loving Stanford. USC is up there though," he said. "This visit really opened my eyes to what the USC program had to offer."
Carlisle compared his style of play to Percy Harvin
