"I didn't know anything about Northwestern," Fox told PurpleWildcats.com on Friday.
The 2015 MLB from Houston (Tex.) Clear Lake HS had been in contact with linebackers coach Randy Bates, who persuaded him to make the trip.
Fox visited other colleges in the past. Some offer during the trip. Some don't. That mutual interest, even early, can completely alter the recruiting process.
So when Pat Fitzgerald offered Fox at the beginning of the visit, the three-star prospect said his "interest peaked for the school."
"I was trying not to smile too big."
One of the best experiences arrived during his meeting with Bates, who outlined his ideal middle linebacker role in the 4-3 defense. Though his Clear Lake team played in the 3-4, Fox wanted to play the 4-3 in college. After, the position group meeting only added to his interest.
"I used to play middle linebacker as a kid," he said. "So I really liked that and I understood the defense really well. And when I was in the player meeting, everyone was laughing but still serious."
Some recruits parse out all trip details; Fox didn't need to. He enjoyed the visit so much that he contemplated a quick commitment. Wake Forest, Mississippi State and Utah had already offered. More were likely coming. Still, he boarded the plane and was immediately considering a pledge.
"I definitely had a very good attitude towards it," Fox said. "I wanted to do a little more research … The degree is phenomenal and they were saying how great it was.
"I started learning more about the football team. Everything seemed right."
This one, it's fair to say, came out of nowhere. Fox called Fitzgerald on Tuesday and was shocked at "how exciting he found it."
"He said: ‘Are you serious? You're not pulling my leg,'" Fox said. "He was doing cartwheels. It's good to know that your coach really wants you."
Fox becomes the first member of the 2015 recruiting class, and he said it only adds to his responsibility.
"It's am honor," Fox said. "I like a leadership role and it adds onto that.
"Coach Fitz wants me to get other recruits here. I can set the standard."
