The 6-foot-3, 225-pound Smith spent Saturday at Notre Dame, touring the campus with Irish coach Brian Kelly and meeting with defensive coordinator Bob Diaco about how he would be used in the defensive scheme.
"I finally got to see it for myself," Smith said. "For a lot of years there were (a lot of people) talking about how great the place was, and everything I heard was true. I got to see it for myself."
A part of the day was designed for Diaco to meet with Smith about being used in the Irish's CAT position, but football wasn't the theme of the day-long visit.
"I learned a lot about family, and just sticking together and it's really not about football," Smith said. "It's about how you carry yourself as a person. We got to eat and it was a nice meal, and got to see the locker room and all the gear Adidas sponsors and things like that. And I got to see the business part of the school. They're No. 1 in the nation.
"I got to see a lot around the campus. I got a 1-on-1 tour with the head coach and he was just telling me about the history and things like that. I got to talk with coach Diaco and he was telling me where my place would be if a go there, and my position. He was breaking the scheme down to me and things like that."
Smith, who also excelled at running back for Bishop Luers, made 55 tackles, including 20 for loss and nine sacks, also had a chance to break down film with Diaco.
"I would be playing the CAT position and they showed me film on it," he said. "They chalk-boarded it a little bit and told me how the whole thing goes."
This won't be the only trip Smith makes. He is one of the most coveted players in the state and counts the Irish, Alabama, Michigan, Oklahoma, USC and Ohio State, where his brother, Rod, plays, among his offers.
However, just because his brother is a Buckeye doesn't mean Jaylon will take that route.
"I'm going to go where I want to go," Smith said. "Whatever is the best fit for me, that's where I'm going to go."
He is also looking to make a decision before his senior season.
"I'm looking for after June, before August," he said. "I'm just keeping everything open and trying to enjoy this experience."
